surface area of a 9 inch cube

1 answer

The formula to calculate the surface area of a cube is:
Surface Area = 6 * side length^2

Given that the side length of the cube is 9 inches, we can plug this into the formula:

Surface Area = 6 * 9^2
Surface Area = 6 * 81
Surface Area = 486 square inches

Therefore, the surface area of a 9 inch cube is 486 square inches.
