Question

A childs pool is in the shape of a rectangular prism with a height of 2 ft and a base that is 4ft wide by 5ft long

during the course of the summer, the childs pool needed to be filled 3 times

how many cubic feet of water were needed to fill the pool during the summer

Answer 1

120 cubic feet

Explanation:

Dimensions of the rectangular prism shaped child's pool is:

Height = 2 ft

Width of base = 4 ft

Length = 5 ft

To find the volume of water to be filled in pool once, we need to find volume of the pool.

Volume of pool =
`l* w* h` cubic feet

where
`l` represents length of base,
`w`represents width of base and
`h` represents height of base.

Plugging in given values.

Volume of pool =
`5* 4* 2` cubic feet

Volume of pool =
`40` cubic feet

∴ To fill the pool once, we will require 40 cubic feet of water.

In summers the child's pool needed to be filled 3 times.

So, the volume of water filled in summers would be 3 times i.e =
`3* 40 = 120` cubic feet (Answer)
