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.
