Cannot be answered with only these measurements. You need to specify a third dimension, (either depth, length, or width, depending on which one you left out here). This is also assuming your pool in square, if not, you need to say what shape your pool is and which aspects of it the numbers you provide are describing (radius, diameter, side length, etc.). If it is an irregular shape, finding the volume of the pool could involve approximating the edge of the pool with a function and using integrals (a type of calculus). Anyway, once you have the volume in cubic feet, multiply it by 7.48 to find the number of gallons in your pool.
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
