Question

The volume of cube is 125 cubic inches . What are the lengths of the sides?

Answer 1

We are given that the volume of a cube is 125 cubic inches. The formula for the volume of a cube is the following:

$V=l^3$

Where:

$l=\text{ length}$

Substituting the value of the volume we get:

$125in^3=l^3$

Now we solve for the length "l" by taking cubic root to both sides:

$\sqrt[3]{125in^3}=\sqrt[3]{l^3}$

Solving the operations:

$5in=l$

Therefore, the length of the cube is 5 inches.
