Is this question dealing with surface area or volume?? (Don’t mind the w•l•h)

marin [14]

Answer:

Step-by-step explanation:

First you must find the number of cubic feet in the pool. (That's volume)

Formula

V = l*w*h

Givens

l =38
w = 22
w = 8

Solution

Volume

V = 38 * 22 * 8

V = 6688 cubic feet.

Gallons

1 cubic foot = 7.5 gallons

6688 ft^3 = x

Proportion

1/6688 = 7.5 / x Cross Multiply

x * 1 = 7.5 * 6688

x = 50160 gallons
