Best Answer

There are 7.48 gallons in 1 cubic foot.

Volume of tank = 100ft x 30ft x 20ft = 60000 ft3.

60000ft3 x 7.48gal/ft3 = 448800gal

Q: How many gallons of water in a tank that is 100 feet x 30 feet x 20 feet?

If this is a round tank, 15 feet wide and 7 feet tall, there would be 1237 gallons.

29,610.94 gallons (rounded)

The tank will hold up to 90 (89.7662) gallons.

The capacity of the tank is 12.468 gallons (rounded) for each inch the tank is long.

Convert everything to feet, then use the formula for the volume of a cylinder. Since the answer will be in cubic feet, you'll then have to convert it to gallons.
