calculate the surface area of a cube with 12-inch edges.

1 answer

To calculate the surface area of a cube, you need to find the area of all six sides and then sum them up.

Since all sides of a cube are equal, you only need to find the area of one side and multiply it by 6.

The formula for finding the area of a square (which represents one side of a cube) is:

Area = side length^2.

Given that the side length is 12 inches, you can substitute it into the formula:

Area = 12^2 = 144 square inches.

Now, multiply this area by 6 (since a cube has six equal sides), so:

Surface Area = 144 * 6 = 864 square inches.

Therefore, the surface area of a cube with 12-inch edges is 864 square inches.
