![]() To find the surface area of a rectangular prism, you need to know the length, width, and height of the prism. Where l is the length, w is the width, and h is the height of the prism. Surface Area of Rectangular Prism Formula For example, if all measurements were in inches, then the surface area would be in square inches. The units for measuring surface area will depend on the units used for the length, width, and height measurements. With those measurements, you can use the formula:įor example, if a rectangular prism has dimensions of length = 3, width = 4, and height = 5, then its surface area would be calculated as:Ģ(3×4 + 4×5 + 3×5) = 2(12+20+15) = 2(47) = 94 To find the surface area of a rectangular prism, you need to know the measure of two adjacent sides (length and width) and the height of the rectangle. Surface Area = 72 square feet How to find the surface area of a rectangular prismĪ rectangular prism is a solid geometric figure with six faces that are rectangles. We can plug these values into our formula to calculate the surface area. Suppose we have a rectangular prism that has dimensions of length 9 feet, width 3 feet, and height 2 feet. Let’s look at an example to see how this formula works. The surface area of a rectangular prism can be found using the formula: In the diagram below, we can see that the length (L) and width (W) are measured in units and the height (h) is measured in inches. To find the surface area of a rectangular prism, we need to know the measure of two sides and the height. ![]() The surface area of a rectangular prism is the sum of the areas of its six faces. ![]() Surface Area of Rectangular PrismĪ rectangular prism is a three-dimensional figure with six faces that are all rectangles. A rectangular prism with two dimensions will have two rectangles on each face, and so on. A rectangular prism with three dimensions will have four rectangles on each face. The number of rectangles on each face depends on how many dimensions the rectangular prism has. The surface area is the sum of the areas of all the faces. The surface area of a rectangular prism can be defined as the total area of all the faces of the prism. Surface Area of a Rectangular Prism Definitions and Examples
