$V=216\text{ft}^3$

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: $$V=(6\text{ft})(6\text{ft})(6\text{ft})$$We multiply to find the volume: $$V=216\text{ft}^3$$
