Answer:

486

Step-by-step explanation:

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

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