Calculate the pool's area and multiply that product by the average depth.1 Then multiply that product by 7.5. (A cubic foot of water contains 7.5 gallons.) Area = 16 x 32 = 512 Average depth = (4 + 7)/2 = 5.5 512 x 5.5 = 2,816 2816 x 7.5 = 21,120 gallons Note 1: If the bottom of the pool doesn't slope evenly from the shallow end to the deep end, the average-depth calculation will be slightly off, not enough to make an appreciable difference in the end result, however.
