Question

the volume of a cube is equal to the cube of the length of one side. if the side length of a cube is 8 feet, which expression represents the volume of the cube? a $8^{2}$ b $8^{3}$ c $8^{4}$ d $3^{8}$

Explanation:

Step1: Recall volume formula for cube

The volume $V$ of a cube with side - length $s$ is given by $V = s^3$.

Step2: Substitute given side - length

Here, $s = 8$ feet. So the volume of the cube is $V=8^3$.

Answer:

B. $8^3$
