For Exercise 41 to 44, 1 f t 3 of liquid corresponds to 7.5 gallons of the liquid.After a devastating rainfall, a basement floor that is 40 ft by 60 ft is covered in 18 in. of water.a) How many cubic feet of water must be pumped from the basement?b) How many gallons of water are represented by the answer in part(a)?

To determine

To find:

The quantity of the water that must be pumped from the basement in cubic foot.

Explanation

Given,

Dimension of the basement floor is 40 ft by 60 ft.

Height of the rainwater in the floor =18 in.

Thus, the dimensions of the rain water in the floor is given by

l=40 ft

w=60 ft

h=18 in.

Of the above three given measures height of the water is measured by the nit of inches while the other two are measured by the unit of foot.

Thus, it is necessary to convert the measure of height from the init of inches to foot. For the units need to be uniform.

1 foot =12 inches.

112 foot =1 inches

To determine

b)

To find:
