Calculate the surface area of a cube with 12-inches edges. How many square inches is the surface area?
A cube has 6 equal faces.
The surface area of each face is determined by squaring the length of one edge: 12 * 12 = <<12*12=144>>144 square inches.
The total surface area of the cube is found by multiplying the surface area of one face by the number of faces: 144 * 6 = <<144*6=864>>864 square inches.
Therefore, the surface area of a cube with 12-inch edges is 864 square inches.
