## How to Convert US Gallons to Feet Cube

*Example: How many feet cube are equivalent to 38.39 US gallons?*

As;

1 US gallons = 0.13 feet cube

38.39 US gallons = Y feet cube

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

Y equals 38.39 times 0.13 over 1

(i.e.) Y = 38.39 * 0.13 / 1 = 4.9907 feet cube

Answer is: 4.9907 feet cube are equivalent to 38.39 US gallons.
