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, 15*15*4*5.9=5000 gallons

Volume Pi x r squared x 4 (depth) Pi = 3.14115926535 r = 1/2 Diameter = 7.5 depth = 4 gallons per cubic foot 7.48 3.14 x (7.5 x 7.5) x 4 x 7.48 = 5284.62 gallons Y-THINK-Y

The volume would be pi*r^2*d = 3.14*7.5^2*4 or about 707 cubic feet. This converts to 5289 gallons. This assumes the water is actually four feet deep which means the pool is a bit higher.

If this is a round pool 15 feet across and four feet deep, the maximum water capacity (filled to the very top) is 5,288.7 gallons.
