## How to Convert Millimeters Cube to Feet Cube

*Example: How many feet cube are equivalent to 18.89 millimeters cube?*

As;

1 millimeters cube = 3.53147E-8 feet cube

18.89 millimeters cube = Y feet cube

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

Y equals 18.89 times 3.53147E-8 over 1

(i.e.) Y = 18.89 * 3.53147E-8 / 1 = 6.67094683E-7 feet cube

Answer is: 6.67094683E-7 feet cube are equivalent to 18.89 millimeters cube.
