total surface area of a 9 inch cube

1 answer

The total surface area of a cube is calculated by adding up the surface area of all six sides of the cube.

The formula for calculating the total surface area of a cube is:
Total Surface Area = 6 * (side length)^2

Given that the side length of the cube is 9 inches, the calculation would be:
Total Surface Area = 6 * (9)^2
Total Surface Area = 6 * 81
Total Surface Area = 486

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