To solve for the width and the length of the pool, you will use the formula for finding the volume of a rectangular prism. You will represent the length and the width of the pool in terms of w, the width.
Please see the attached picture for the work.
The width of the pool is 20 feet.
The length of the pool is 3 x 20 ft or 60 feet.
