Work Step by Step

To find the volume of a rectangular prism, we simply use the formula $V=lwh$, where $l$ is the length, $w$ is the width, and $h$ is the height. We plug in the values for length, width, and height, as seen on the diagram: $$V=(5\text{in})(8\text{in})(2\text{in})$$We multiply to find the volume: $$V=80\text{in}^3$$
