Question 273832: gina has a sheet of cardboard that measures 9 feet by 6 feet. she uses scissors and tape to make the entire sheet of cardboard into closed box that is a perfect cube. What is the surface area of the box Answer by checkley77(12844) (Show Source):
You can put this solution on YOUR website! 6*9=54 ft^2 is the surface area of the cardboard.
6x^2=54 is the surface area of the cube.
x^2=54/6
x^2=9
x=sqrt9
x=3 ft. length of all sides of the cube.
