Question

6. Annie has a cube that has a side length of 9 cm. What is the surface area of the cube?​

Answer 1

486

Explanation:

• Surface area means the area of each side added up
• In a cube, every side is the same

1. the area of one side = 9 * 9 = 81, since it is a square (width*height) and width and height are the same.
2. in a cube there are 6 sides
3. so there are 6 sides with area 81
4. 81 * 6 = 486
