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.
If the depth is 6-ft everywhere ... no deeper places or shallower places ...then the volume is18' x 36' x 6' = 3,888 cubic feet3,888 cubic feet = 29,084 gallons (rounded)That's the volume of the pool, up to the rim. I haveno way to know how much water may be in it.
If the pond is uniformly 6-feet deep it would contain about 1,955,109 gallons of water.
how many gallons of water does a swimming pool 15 feet by 4 feet deep hold
17,953.2 gallons
250 ft3 = 1870.13 US gallons
The pool holds approximately 10,560 gallons of water.
24,685.79 gallons
1,770 gallons.
6,200 gallons.
3,398.4 gallons.
5,974 gallons.
Depends on the depth of the water. If you go to four feet deep the total would be about 13,594 gallons.
