Answer:
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 =
cubic feet
where
represents length of base,
represents width of base and
represents height of base.
Plugging in given values.
Volume of pool =
cubic feet
Volume of pool =
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 =
cubic feet (Answer)
