Calculate the surface area of a cube with 12-inch edges. How many square inches is the surface area?(1 point)

To calculate the surface area of a cube, we need to determine the area of each face and then sum them up.
The area of one face of a cube is equal to the length of one side squared. In this case, the length of one side is 12 inches. So the area of one face is 12^2 = 144 square inches.
A cube has 6 faces, so to calculate the total surface area, we multiply the area of one face by 6.
Total surface area = 144 square inches * 6 = 864 square inches.
Therefore, the surface area of the cube is 864 square inches.
