Calculate the surface area of a cube with 12-inch edges. How many square inches is the surface area? (1 point)
A cube has six equal square faces. Since each edge of the cube is 12 inches, the surface area of each face is 12 inches x 12 inches = <<12*12=144>>144 square inches.
To find the total surface area of the cube, we multiply the surface area of one face by the number of faces: 144 square inches/face x 6 faces = <<144*6=864>>864 square inches.
The surface area of the cube is 864 square inches. Answer: \boxed{864}.
