Volume Of Rectangular Prism – Prisms are three-dimensional objects that have two equal bases or ends, flat surfaces or sides, and equal cross-sections along their length. A cube is a prism, but unlike a cube of 6 equal squares, a rectangular prism has six rectangular sides and 12 edges. Its length, width and height form 3 pairs of equal rectangular sides: up-down, left-right and front-back. Examples of rectangular prism-shaped objects are shoe boxes, books, buildings, and cabinets.
The total area of a rectangular prism is the sum of the areas of all six rectangular sides. Recall that the area of a rectangle is the product of its length and width:
Volume Of Rectangular Prism
The volume of a rectangular prism is the amount of total area it occupies and can be defined as the product of its length, width, and height.
Math Formulas For Basic Shapes And 3d Figures
The volume of a rectangular prism also reveals its capacity – or the amount of space that can be filled inside the object. Volumes are expressed in cubic units, for example m
. If the volume refers to the capacity of the prism, it can also be expressed in liters (L) or milliliters (mL).
Finally, find the volume by substituting the given numbers into the volume formula and multiplying.
How many rectangular barrels can fit in a rectangular container 5 m long, 3 m wide, and 4 m high, if each barrel is 0.5 m long, 15 m wide, and 2.5 m high?

Check out some of our other blog posts or invest in your future with one of our self-study courses! Hi! Today we will examine the most common 3D figure, the rectangular prism, also known as the rectangular body. As with most 3D figures, we can use relatively simple formulas to calculate volume and area. But before we do that, we need to define some concepts.
Question Video: Finding The Volume Of A Rectangular Prism By Counting Unit Cubes
A rectangular prism or rectangular body is a 6-sided object where each side, also called a face, is a rectangle. It has 12 edges and eight vertices, and all angles are right angles.
Now let’s make a rectangular prism from small centimeter cubes. Let’s start with the lowest level and place them in a (5x 3) rectangle. At this point we have used 15 cubes to make our shape and have successfully created a rectangular prism.
Notice that if we multiply the dimensions of our (5xx) cube, we get our volume! This is because the formula for the volume of a rectangular prism is the product of the dimensions:
An example of a real volume problem is when you have to pour a foundation for a rectangular building – you have to measure the area of each side of the building to know how much concrete to make. So if we need to pour a foundation of (42.5texttimes}times}) (this is the height), we can use these dimensions to find the volume of our foundation by plugging it into our formula:
What Is The Volume Of The Rectangular Prism Shown? Please Answer Asap
This problem allows us to see square centimeters, but most area problems do not show squares. We will only know the dimensions of the rectangular prism, so:
Here we can see that our prism is 10 meters long, 5 meters wide and 4 meters high. The corresponding edges of the opposite sides will be the same since it is a rectangular prism. To determine the area, I can use the formula for the area of rectangular prisms:
This formula gives us the area if we include our length, width, and height. Don’t confuse which side is length, width, and height. Depending on how the prism is positioned on the page, 10 m may appear to be the length, but it may actually be the width or height. Does not matter! But for our purposes, say 10 m long, 5 m wide and 4 m high. If we replace everything, it looks like this:
Notice that we left the units when we replaced them. Now, when we evaluate each expression, we get that the area is equal to:
Math Down Under: Rectangular Prisms
Notice that our units ended up being square, which is what we need for the area. Finally, we just add the conditions so that our area is 220 square meters.
It’s not too difficult, but it’s worth taking a moment to see what this formula actually does:
The first term, (2lw), is twice the length and width. This calculates the area of the bottom and top of a rectangular prism. There are 2 to double the area of both sides. The middle term, (2lh), is twice the length and height. In other words, the front and back of the prism. The final term, (2wh), is twice the width and height. In other words, the left and right sides of the prism.
So the formula simply finds the area of all 6 sides of the 2 prisms at once. This means that if we forget the formula, we can simply find the area of each side separately and add it up. It takes a little longer, but it totally works.

I hope this video on surface area and volume of rectangular prisms was helpful. Thanks for watching and happy learning!
Rectangular prisms have 6 faces. Add the areas of the 6 sheets to calculate the area. This can be done using the following formula:
Drea works for a swimming pool installation company. What will be the volume of the pool if Drea fills the pool to the 4 meter mark?
George built an aquarium that connects two tanks with a middle section. This allows the fish to swim back and forth between the chambers. How much water can fit in the whole aquarium?
Volume Of Rectangular Prism
Calculate the volume (V=lwh). The aquarium consists of three rectangular prisms. Add the volumes of the three prisms. Volume is the total amount of three-dimensional space occupied by an object. Volume is measured in cubic units. So if an object has a volume of 1800 cubic units, it means that it is made up of 1800 cubic units. A prism is a polyhedron with the same base, a straight rectangle, and the same cross-section. There are many different shapes of prisms. In the article below, we will learn about a rectangular prism and the formula for the volume of a rectangular prism. Read on to learn how to find the volume of a rectangular prism.
A rectangular prism is a three-dimensional shape with six faces. All faces of the prism are rectangular. A rectangular prism is shaped like a cube. This polyhedron has two pairs of congruent and parallel bases. It has six faces, 12 sides and eight vertices. Some common names for rectangular prisms are rectangular hexagon, rectangular parallelepiped, and rectangular prism.
The bases of a rectangular prism are perpendicular to the other sides. This prism is in the form of a geometric solid. Its base is a polygon, and its vertical sides are perpendicular to the base. The base and apex of a rectangular column have the same shape and size. It is called a “rectangular” prism because its base and sides are right angles.
On the contrary, in an oblique rectangular prism, the bases of the prism are not perpendicular to the other faces. In this case, the height of the rectangular prism is drawn perpendicularly from the top of one base to the other base of the rectangular prism. However, the same formula can be used to calculate the volume of a rectangular prism regardless of the type of prism.
Paper Rectangular Prism
The volume of a rectangular prism is the total area occupied by the rectangular prism. The volume of a rectangular prism can be obtained by multiplying its length, width, and height, in the same way as for a rectangle. So the unit of measurement for the volume of a rectangular prism is cm
The base of a rectangular prism is a rectangle. So the area will be l × w. Multiplying this area by the height of the prism yields the volume of the rectangular prism.
To calculate the volume of a rectangular prism, we must first make sure that all dimensions of the prism have the same units. The following steps will help you estimate the volume of a rectangular prism.
Step 2: Next, we identify the height of the prism. The height of the prism is perpendicular to the base of the prism.
