Question

Please Help! Explain if possible :-)

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

During the course of the summer, the child’s pool needed to be filled 3 times.

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

A. 40ft³
B. 80ft³
C. 120ft³
D. 160ft³

Answer 1

I got C for this one...........

Answer 2

Answer: C.
`120\ ft^3`

Explanation:

The given dimensions of pool :-

Length (l)= 5 ft.

Width (w)= 4 ft.

Height (h)= 2 ft.

The volume of rectangular prism is given by :-

`\text{V}=lwh`

Then, the volume of swimming pool is given by :_

`\text{V}=5*4*2=40\ ft^3`

Since, during summer, the child’s pool needed to be filled 3 times.

Therefore, The amount of water were needed to fill the pool during the summer =
`3*40=120\ ft^3`
