Answer:
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:
[tex]\text{ Height of water in the pool}=5-1\frac{1}{2}=3\frac{1}{2}\text{ feet}[/tex]
Therefore, the number of cubic feet of water it takes to fill the pool is the volume of water in the pool.
[tex]\begin{gathered} \text{ Volume}=\text{ Length}\times\text{ Width}\times\text{ Height} \\ =20\times10\times3\frac{1}{2} \\ =200\times\frac{7}{2} \\ =700\text{ cubic feet} \end{gathered}[/tex]
It takes 700 cubic feet of water to fill the pool.
