What is the surface area of a cube with a side length of 9cm?

1 answer

The surface area of a cube is calculated by finding the area of each of the 6 faces and adding them together.

The formula for the surface area of a cube is: 6 * (side length)^2

So, for a cube with a side length of 9cm, the surface area would be: 6 * (9cm)^2 = 6 * 81cm^2 = 486cm^2

Therefore, the surface area of a cube with a side length of 9cm is 486 square centimeters.
