The surface area \( A \) of a cube can be calculated using the formula:
\[
A = 6s^2
\]
where \( s \) is the length of one edge of the cube.
Given that the edge length of the cube is 4 inches, we can substitute \( s = 4 \) inches into the formula:
\[
A = 6(4)^2
\]
Calculating \( 4^2 \):
\[
4^2 = 16
\]
Now, multiply by 6:
\[
A = 6 \times 16 = 96
\]
Thus, the surface area of the cube is
\[
\boxed{96} \text{ inches}^2.
\]
\[
A = 6s^2
\]
