To calculate the surface area of a cube, you need to find the area of each face and then add them up.
The area of one face of a cube is calculated by multiplying the length of one edge by the length of one edge, so it would be 12 inches x 12 inches = 144 square inches.
Since a cube has 6 faces, you need to multiply the area of one face by 6 to get the total surface area.
Therefore, the surface area of a cube with 12-inch edges is 144 square inches x 6 = 864 square inches.
