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.
There is not enough information in your question to tell you. A gallon is 0.133681 cubic feet. As such we would need three dimensions to come up with the correct answer. Assuming the pool is exactly 1 foot deep the number would be 9,335.65 gallons. Multiply this number by the average depth of the pool to come up with your answer.
You haven't provided enough information - what are the units of measurement (24 whats, feet, metres) and how deep is the pool...?
