She will need #486# units of wrapping paper.

Explanation:

The amount of wrapping paper Anna needs is the surface area of the cube.

Since the shape is a cube, all of its linear dimensions are the same.
Generally, the surface area of a figure is the sum of the areas of its sides, which a cube has #6# of. The area of one of the sides is simply #9*9# as it is a square.

#SA=6*81#

#SA=486#
