How many gallons of water in a 16 foot round above ground swimming pool fifty-four inches deep?

Answer 1

Here's a formula for round pools:

distance across*distance across*depth*5.9

for rectangles:

length*width*depth*7.5

or for a deep end:

length*width*((shallow end depth + deep end depth)/2)*7.5

so in your case, 24*24*4.3*5.9=15000 gallons

Answer 3

A 24-foot round pool with 50 inches of water in it is holding about 14,158 gallons.
