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.
8ft³= 226.5348L
Slightly more than 226 liters in 8 cubic feet
5 ft x 8 ft x 15 in = 50 cubic ft 50 ft3 = 1.416 m3 = 1416 L
All you have to do to find the volume of a swimming pool is multiply the length x width x average depth x gallons in a cubic foot (7.48). In your case it would be 38x22x5.5x7.48=34,393 gallons.
2.5 cubic feet = 70.8 liters.
The volume is 13592 litres, approx.
5ft x 5ft x 8ft equals 5,663.37 liters.
About 39,397 liters.
About 129,715 liters.
About 45,025 liters.
There are 100 inches in 8ft 4in
Cross multiply then divide, 20*8 divided by 40= 40 gallons
