Question

The volume of a cube is found using the formula l^3, where l is the side length. What is the volume of a cube, in cubic feet, that is 3/5 of a foot long?

Answer 1

well the volume is simply

\[V = (\frac{3}{5})^3 ft^3\]

which can be written as

\[V = \frac{3^3}{5^3} ft^3\]

just evaluate the numerator and denominator for the answer
