Solve for Volume:įind the volume of a rectangular prism with the following measurements: Note: Remember that all measurement units should be the same before you compute the volume. If the volume refers to the prism’s capacity, it can also be expressed in liters (L) or milliliters (mL). Volumes are expressed in cubic units such as m 3, km 3, and cm 3. The volume of a rectangular prism also tells its capacity – or the amount of space inside an object that can be filled. Where l = length of the prism w = width of the prism and h = height of the prism. Use this formula to find the volume of a rectangular prism: The volume of a rectangular prism is the total amount of space it takes up, and can be defined as the product of its length, width, and height. How to Find the Volume of a Rectangular Prism: Therefore, the surface area of the rectangular prism is 112cm². Plug the figures into the formula for surface area and solve. Solve for Surface Area:įind the surface area of a rectangular prism with the following measurements:
Make sure all units are the same before you compute the surface area. Note: Surface areas are expressed in cubic units such as in 2, cm 2, km 2, m 2. Where: l = length of the prism w = width of the prism and h = height of the prism. Use one of these formulas to find the surface area of a rectangular prism: Related Reading: Area of a Rectangle – Formula & Examples Recall that the area of a rectangle is the product of its length and width: A = l
The total surface area of a rectangular prism is the sum of all the areas of its six rectangular sides. How to Find the Surface Area of a Rectangular Prism: Examples of objects shaped like a rectangular prism are shoe boxes, books, buildings, and cabinets. It has a length, width, and height that make up 3 pairs of equal rectangular faces: top-bottom, left-right, and front-back.
A cube is a prism, but unlike a cube that has 6 equal square faces, a rectangular prism has six rectangular faces and 12 edges. Prisms are three-dimensional objects with two equal bases or ends, flat surfaces or sides, and the same cross-section along its length. Let’s learn how to find the surface area and volume of a rectangular prism.
