Question

A swimming pool had a volume of 7,200 ft^3. It has a depth of 9 feet and a width of 20 feet. What is the length of the swimming pool

Answer 1

Given data:

The volume of the swimming pool is V=7,200 ft^3.

The width of the pool is b=20 feet.

The depth of the pool is d=9 feet.

The expression for the volume of the pool is,

`V=l* b* d`

Substitute the given values in the above expression.

`\begin{gathered} 7,200ft^3=l(20\text{ ft)(9 ft)} \\ l=40\text{ ft} \end{gathered}`

Thus, the length of the pool is 40 ft.
