The surface area \( A \) of a cube can be calculated using the formula:
\[
A = 6s^2
\]
where \( s \) is the side length of the cube.
For a cube with a side length of 8 inches:
\[
A = 6(8^2) = 6(64) = 384 \text{ square inches}
\]
So, the surface area of the cube is **384 square inches**.
\[
A = 6s^2
\]
where \( s \) is the side length of the cube.
