Basic Rectangular Prism Rules
Are you a math student? Then you should learn more about prisms, especially a rectangular prism and what makes it unique. Basically, there are several important rules that identify a 3-dimensional shape of any prism. Keep in mind that calculating its volume is quite easy if you know its height, length, and width, but don’t forget about the everyday examples of a rectangular prism because they may come in handy while doing your homework. It’s all about a six-sided object that is very familiar with all people, a simple box. You can also take into account a shoebox, a brick, and other similar objects to get a better idea of what a rectangular prism is. If you find it a bit hard or frustrating to complete relevant assignments, the good news is that there are many skilled and reputable freelancers whose contacts are easy to find online and who can do any homework, including an accounting paper, at quite reasonable rates.
First, you should start with learning more about prisms, which are specific shapes with different rules and characteristics that make them stand out. They can be called multiple-sided closed shapes or polygons that are joined together, thus forming enclosed 3-dimensional shapes. For instance, a simple box is a prism because it contains 2 rectangles or squares that are joined together to make enclosed 3-dimensional figures, such as a rectangular prism. When it comes to 2-dimensional shapes, they make a bottom and a top (faces) of any prism. This means that any stacks, boxes, and legal pads are prisms as they are 3-dimensional objects that have congruent polygons as their faces. What about important prism rules?
- As you already know, the faces of a rectangular prism must be polygons. So, if you think that cylinders are prisms, you’re wrong because they can’t fit the definition as their faces are ovals and circles without sides so that they are not polygons.
- All sides of a rectangular prism must be parallelograms that are quadrilaterals with opposite parallel sides. Take a look at a box and a triangular prism, and you will understand that all of their sides follow this simple rule.
- The faces of a rectangular prism should be parallel. If you see any figure that has one angle that lies at the other one, this means that they will intersect at some point so that it can’t be called a rectangular prism. That’s because sides can’t be parallelograms if all faces are not parallel.
- All bases should be congruent or have the same size and shape. If any face is not congruent, you can’t call a given figure a prism.
- Take a cross section of any rectangular prism parallel to faces, and you will see that it’s congruent with all of its faces. Keep in mind that this happens only faces all faces are parallel and congruent, no matter where you cut a given figure.
For example, you can think of a rectangular prism as a loaf of bread, and if you slice it parallel to ends (regardless of where you cut), all slices will have the same shape.
Different Types of Prisms
Once you study these basic rules, you need to understand that there is always something that won’t fit them to write your research proposal on this subject successfully and get high grades.
- Oblique prisms. Remember that angles between faces and sides are not always right angles, and these figures have slanted sides, but their faces are still parallel and congruent.
- Regular prisms. Their bases are regular polygons.
- Irregular prisms. As their name suggests, their bases are irregular polygons.
- Right prisms. When it comes to your mla essay format about them, take into account that their lateral faces are squares or rectangles.
- The bases of such prisms are parallelograms.
- Their faces are rectangular.
It’s also possible to categorize all prisms according to their base, and this is how you will get:
- Triangular prisms (their bases are triangles).
- Pentagonal prisms (pentagons are their bases).
- Hexagonal prisms (their bases are hexagons), etc.
Basic Questions about a Rectangular Prism
As a good student, you should know that a rectangular prism is a three-dimensional solid shape, and it has 6 faces (they all are rectangle in their shape). To study this subject, you need to learn specific formulas used to determine the surface area and volume of a rectangular prism, and that’s why it’s necessary to know how to answer a few basic questions.
What is a rectangular prism ? Basically, it’s a prism that consists of 2 rectangular bases and 3 rectangular sides. It’s a polyhedron with 2 parallel and congruent bases, and all of its cross-sections are parallel to base faces and they are similar to rectangles. This means that a rectangular prism is just like a cuboid.
What is the volume of a rectangular prism ? It’s a certain measurement of its occupied units that must be represented in cubic units. Besides, you can define it as a number of units needed to fill this prism. Keep in mind that the volume of a rectangular prism must be equal to the area of base times its height.
What about a lateral surface area? It’s the sum of the total surface area of all faces without a base. When dealing with any rectangular prism, its lateral surface area must be equal to the perimeter of its base times its height.
What is its surface area? It’s all about a measure of how much exposed area a rectangular prism actually has and it must be expressed in square units. You can call it the sum of the entire lateral surface area and twice its base area.
Tips on How to Graph a Rectangular Prism
You should already know that a prism with rectangular bases is called rectangular, and it’s a right one if all of its angles are right and it has 6 faces that are rectangles. Besides, a rectangular prism with the bases that aren’t aligned one above the other directly is called oblique. This figure also has 6 rectangular faces and 3 sets of 2 congruent sides. If you need to illustrate this concept in some concrete terms, it’s advisable to make a standard model of a rectangular prism with the help of cubic blocks or simple construction paper.
Let’s start with a paper prism, and there are certain steps that should be taken to end up with good results. First, you need to review given dimensions because it’s necessary to know the right height, width, and length before you start building any rectangular prism. Be sure to write down important dimensions and keep referring to them throughout the entire process.
Then you should measure that cut 2 lengths by width rectangles. Use a pencil and a ruler to draw 2 rectangles on a piece of construction paper. Make sure that the length of each one matches the length of your final rectangular prism, while the width of 2 rectangles must match its width. Once both rectangles are drawn, you should use a ruler to measure them once again because they must have equal sizes and match the length and width of your rectangular prism quite accurately. If you’re sure that they have the right width and length, feel free to cut them out by using sharp scissors. Remember that both rectangles will form the bottom and top of your desired figure.
The next step that should be taken is measuring and cutting 2 lengths by height rectangles. This is when you need to use a pencil and a ruler to draw 2 rectangles from quality construction paper. Make sure that their length matches the length of your rectangular prism, while their width matches its height. Don’t forget to re-measure both rectangles to ensure that they are accurate before using sharp scissors to cut them. Take into account that they must form the back and front of your rectangular prism evenly.
You also need to measure and cut 2 widths by height rectangles, so sketch them on good construction paper using a pencil and a ruler, but remember that the length of each one must match the width of your rectangular prism and their width must match its height. Once you draw both rectangles, you should measure them twice to ensure a high level of accuracy before you cut them with scissors. They must form the right and left sides of the desired rectangular prism.
Take 4 rectangles into one strip loosely and line up your length-by-width and length-by-height rectangles while alternating between them. You need to tape all length sides together on 1 side of your construction paper. Ensure that these paper rectangles are lined up in the right order and avoid placing the identical ones next to one another. When dealing with your writing a critical essay on this subject, note that all rectangles must be lined up so that all length sides must lie next to the length sides of your adjacent rectangle. Be sure to apply tape strips to every shaped edge, and when this process is complete, all of your rectangles must be taped together into 1 strip.
It’s necessary to join its end, so fold it to let 2 unattached length-side ends meet. As you keep folding, ensure that you use fingers to crease a tape between edges, as this is what will make this process much easier. If this task seems a bit intimidating, ask reliable and talented freelancers for help because they can complete any academic assignment, including your writing an argumentative essay.
You should end up with something that resembles a rectangular cube so that the shape of your rectangular prism is almost complete, but 2 important sides are still missing. That’s why you need to attach remaining rectangles while ensuring that their height sides match the height side of your rectangular prism. Likewise, the width sides of all rectangles should match the width side of a given rectangular prism. You should start with taping 1 side of every rectangle in place, and then do the same with opposite sides, and this is what will guarantee better security. Finally, measure the sides of your finished product by using a ruler because all height, width, and length dimensions must match the necessary ones that you have to fulfill. Once you take the above-mentioned steps, your rectangular prism is complete.
How to make a block rectangular prism ? This option may seem a bit easier to some math students, but it still requires certain steps to be taken. Everything starts with reviewing the necessary dimensions because you need to know them to build the right rectangular prism. If you prefer to simplify this process, think about working with generic cubic units instead of using other measurements. Then you need to gather enough blocks, but make sure that their number can match the volume of your final rectangular prism. If you’re not aware of its volume, it’s necessary to multiply its height, width, and length.
You also need to create a line of special blocks to match the number of cubic units or the length of the final figure and try to keep a line as even as you can. In addition, you should create the second line by taking similar steps. Determine if the total number of blocks matches the width of your final rectangular prism. It’s required to complete a rectangle and stack enough blocks to match the height of your desired figure. Remember that this process should be repeated over your entire rectangle, and once it’s complete, you will end up without any excess blocks.
The only thing that is left is to count blocks to measure sides because they make up the height, width, and length of your rectangular prism. They should match the number of cubic units for its every side, and don’t forget to calculate a surface area by multiplying the width and length of any face. The volume of your prism is also easy to calculate by multiplying the number of blocks.
