A: 384 square inches
To calculate the surface area of a cube, you need to find the area of each face and then add them all together. Since all the faces of a cube are the same size, the formula for the surface area of a cube with side length "a" is: 6a^2
In this case, the side length is 8 inches, so the formula becomes: 6(8)^2 = 6(64) = 384 square inches. Therefore, the correct answer is A.
