The formula for the total surface area \(A\) of a cube is given by:
\[
A = 6s^2
\]
where \(s\) is the length of a side of the cube.
Given that the sides of the cube are 8 inches, we can substitute \(s = 8\):
\[
A = 6(8^2) = 6(64) = 384
\]
Thus, the total surface area of the cube is:
\[
\boxed{384 \text{ in}^2}
\]
\[
A = 6s^2
\]
where \(s\) is the length of a side of the cube.
