Question

I am confused and need this question quick It’s number 3

Answer 1

700 cubic feet

Explanation:

The pool is to be filled with water until it is 1 1/2 feet from the top of the pool. Therefore, the height of the water in the pool is:

`\text{ Height of water in the pool}=5-1(1)/(2)=3(1)/(2)\text{ feet}`

Therefore, the number of cubic feet of water it takes to fill the pool is the volume of water in the pool.

`\begin{gathered} \text{ Volume}=\text{ Length}*\text{ Width}*\text{ Height} \\ =20*10*3(1)/(2) \\ =200*(7)/(2) \\ =700\text{ cubic feet} \end{gathered}`

It takes 700 cubic feet of water to fill the pool.
