A cube-shaped gift is 11 centimeters long. What is the least amount of wrapping paper you need to wrap the gift?

Since it's a cube, all the sides are the same......that is.....width = length = height

 

So.......the amount of wrapping paper represents the surface area

 

And the surface area   =  6* (side)^2  =    6*(11)^2  =  6 * 121   =  726  cm^2

 

 

cool cool cool
