Answer:
120 cubic feet
Step-by-step 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 = [tex]l\times w\times h[/tex] cubic feet
where [tex]l[/tex] represents length of base, [tex]w[/tex]represents width of base and [tex]h[/tex] represents height of base.
Plugging in given values.
Volume of pool = [tex]5\times 4\times 2[/tex] cubic feet
Volume of pool = [tex]40[/tex] 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 = [tex]3\times 40 = 120[/tex] cubic feet (Answer)
