How many gallons in a 18 x 36 foot pool with a nine foot deep end and a 3 foot shallow end?

Answer 1

Hard to say exactly but you can get a rough estimate with the information you gave by assuming that it's a constant downsloping grade from one end of the pool to the other. Using that, then you'll have roughly 15700 gallons.

Answer 2

Assuming it is filled to the top, an 18 foot diameter, 3 foot deep pool holds 5,711 gallons. Take the radius in feet (half the diameter), square it, multiply by pi (3.1416) to get area in square feet. Area times depth in feet gives you cubic feet. Cubic feet times 7.481 (gallons per cubic foot) gives you gallons. So: 9^2 (81) times 3.1416 times 3 times 7.481 = 5711.06

Answer 3

That is not enough information to tell you how many gallons are in the pool.

The length/width of the deep/shallow end individually are needed for an approximation.

I can give you the min and max gallons of the pool though.

A gallon is 231/1728 cu. ft.

Assuming the whole pool was 5 ft deep: 18 ft X 38 ft X 5 ft = 3420 cu. ft = 457.1875 gallons maximum.

Assuming the whole pool was 3 ft deep: 18 X 38 ft X 3 ft = 2052 cu. ft = 274.3125 gallons minimum.

Answer 4

Impossible to say unless the depth of the shallow end is also known.

Answer 5

49,000 litres, 12945 US gallons or 10780 Imperial Gallons. See calculation and conversion charts on web link.

Answer 6

That sounds exactly like our pool. The builder (Budd's Pools) says it is 22,000 gallons.

Answer 7

About 24,000 gallons

Answer 8

avg 26700 gal
