To calculate the surface area of a cube, we need to find the area of all six sides and add them together.
Since all sides of a cube are equal, we can calculate the area of one side and then multiply it by 6 to get the total surface area.
The formula for the area of a square is side length squared.
In this case, the side length of the cube is 12 inches. So the area of one side is:
12 inches * 12 inches = 144 square inches.
To find the total surface area, we multiply the area of one side by 6:
144 square inches * 6 = 864 square inches.
Therefore, the surface area of the cube is 864 square inches.
Calculate the surface area of a cube with 12-inch edges. How many square inches is the surface area? (1 point)
