To calculate the surface area of a cube, you can use the formula:
\[ \text{Surface Area} = 6s^2 \]
where \( s \) is the side length of the cube.
For a cube with a side length of \( 8 \) inches:
\[ \text{Surface Area} = 6 \times (8)^2 \] \[ = 6 \times 64 \] \[ = 384 \text{ square inches} \]
So the surface area of the cube is 384 square inches.
