hi
It depends on how long the pool is.
8,258.494 gallons.
8x2x1=16
The Panama Canal is 1400 feet long, 180 foot wide and 60 feet deep.
1795 gallons, if you fill it to the brim.
There are 7.48 gallons of water in a cubic foot, so the answer is 1,000,000 / 7.48 = 133,690 ft3 Using approximate figures, if your lake is an average of thirty feet deep and fifty feet wide, it would have to be about ninety feet long. If you are in the UK, your lake would be 160,543 ft3 and thirty feet deep, fifty feet wide and one hundred and seven feet long.
(20' x 12' x 4') = 960 cubic feet
