Bot GPT 3.5 To find the surface area of a cube, you need to find the sum of the areas of all 6 faces. Since each face of a cube is a square, and the edge length of this cube is 12 inches, the area of each face is 12 inches x 12 inches = 144 square inches.
Since there are 6 faces, the total surface area of the cube is 144 square inches x 6 = 864 square inches.
