The short answer is approximately 30,000 U.S. gallons is the capacity of a 20' x 40' pool.
Determine your pool volume by with these easy to use formulas:
Rectangular Pools: Length x Width x Average Depth x 7.5 = Gallons
Oval Pools: Length x Width x Average Depth x 5.9 = Gallons
Round Pools: Diameter x Diameter x Average Depth x 5.9 = Gallons

Zero... Pools have three dimensions not two.
Lenght x Width x Average Depth x 7.48 = Volume in Gallons
with a deep end of 9 feet it is approximately 37,000 gal
Most 20 x 40 inground pools, assuming hopper depth of 8 feet, shallow depth of 42 inch, hold roughly 35,000 gallons. With Average depth of 5.5 feet, would hold about 34,760 gallons.

How many gallons of water for a 15'x30' swimming pool?
13,346 gallons per vertical foot.
It is 30.6 cubic feet = 190.3 Imperial gallons.
One cubic foot of water is 7.4805 gallons.
There are 7.48052 US gallons per cubic foot.
There is NO way to calculate this without knowing how deep the pool is filled!
How many gallons will fit into a 24 foot diameter x 4 foot high round swimming pool
There are 13,536 gallons in a 24 foot diameter pool that has 4 feet of water. Not true for a pool that is 4 feet in height. This would hold less than 4 feet of water.
