Asheet of cardboard measures 9 feet by 6 feet. gina makes the entire sheet of cardboard into a closed box that is a perfect cube. what is the surface area of the box?

I'd call this a trick question ... at least one that's trying hard to distract you.

It makes no difference what shape Gina decided to construct with her cardboard.
Whether it was a cube, a sphere, a pyramid, or a crumpled up ball of cardboard.
As long as she used "... the entire sheet of cardboard ...", the surface area stays
the same as it was when it was just a flat sheet.

(9-feet x 6-feet) = 54 square feet
