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

C.

Step-by-step 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 :-

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

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 =

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p
