Louis built a swimming pool. The depth of the swimming pool is 5 feet. What is the volume of water that it will take to fill the

julia-pushkina [17]

Answer:

For a rectangular prism-like swimming pool: $V = w\cdot l \cdot h$ . $V = 360\,ft^{3}$ when $h = 5\,ft$ , $l = 12\,ft$ and $w = 6\,ft$ .

Step-by-step explanation:

Let assume that swimming pool has a rectangular base and depth is the same at any point at the bottom. In addition, let $w$ and $l$ be the width and length of the swimming pool. Then, the volume needed to fill the swimming pool is:

$V = w\cdot l \cdot h$ , where $h$ is the depth of the pool.

Let be $h = 5\,ft$ , $l = 12\,ft$ and $w = 6\,ft$ . The volume of the swimming pool is:

$V = (6\,ft)\cdot (12\,ft)\cdot (5\,ft)$

$V = 360\,ft^{3}$
