Explanation:

Step1: Recall surface - area formula

The surface - area formula for a cube is $SA = 6s^{2}$, where $s$ is the side length of the cube.

Step2: Substitute side - length value

Given $s = 3$ in. Substitute $s = 3$ into the formula: $SA=6\times(3)^{2}$.

Step3: Calculate the result

First, $(3)^{2}=9$, then $6\times9 = 54$.
