Calculate the surface area of a cube with 12 inch edges. How many square inches is the surface area?
The formula to calculate the surface area of a cube is 6 * (edge length)^2.
In this case, the edge length is 12 inches.
Substituting the values into the formula:
Surface area = 6 * (12 inches)^2
Surface area = 6 * 144 square inches
Surface area = 864 square inches
Therefore, the surface area of a cube with 12-inch edges is 864 square inches.
