How many gallons of water are there in a 15 X 24 foot swimming pool that is 4 feet deep?

V = lwh

where V is volume, l is length, w is width, and h is height.

In this case, the length is 24 feet, the width is 15 feet, and the height is 4 feet. So the volume of the pool is:

V = 24 x 15 x 4 = 1440 cubic feet.

There are 7.48 gallons in one cubic foot, so the pool contains:

1440 cubic feet x 7.48 gallons per cubic feet = 10,752 gallons.

Therefore, there are 10,752 gallons of water in the pool.
