To wrap a cube-shaped box, you need to cover all six sides of the cube with wrapping paper.
The surface area of a cube is found by finding the area of one face and then multiplying by 6.
The area of one face of the cube is the length of one side squared
12 inches * 12 inches = 144 square inches.
Therefore, the total amount of wrapping paper required is 144 square inches * 6 = 864 square inches.
So the correct answer is 864 sq inches.
