Question

1. if a cube is 3 inches on each edge, what is its volume?

Explanation:

Step1: Recall volume formula

The volume formula for a cube is $V = s^3$, where $s$ is the side - length of the cube.

Step2: Substitute side - length value

Given $s = 3$ inches, we substitute it into the formula: $V=(3)^3$.

Step3: Calculate the volume

$(3)^3=3\times3\times3 = 27$ cubic inches.

Answer:

27 cubic inches
