## How to Convert Feet Cube to US Gallons

*Example: How many US gallons are equivalent to 42.95 feet cube?*

As;

1 feet cube = 7.481333 US gallons

42.95 feet cube = Y US gallons

Assuming Y is the answer, and by criss-cross principle;

Y equals 42.95 times 7.481333 over 1

(i.e.) Y = 42.95 * 7.481333 / 1 = 321.32325235 US gallons

Answer is: 321.32325235 US gallons are equivalent to 42.95 feet cube.
