I'm assuming that the pool is circular?
If so, volume is equal to pi x 13.5^2 x 4 = 2290 cubic feet.
One gallon is equivalent to 0.13368 cubic feet.
So total = 2290 / 0.13368 = 17130 (to 4 s.f.)
Cannot be answered with only these measurements. You need to specify what shape the pool is. Also, for a rectangular pool, the length, width and depth are needed. For a round pool, the diameter and depth are needed.
