if anyone can hlp me plz A cube-shaped gift is 11 centimeters long. What is the least amount of wrapping paper you need to wrap the gift?

The least amount of wrapping paper needed is the surface area of the cube.

 

A cube has six square faces, and each face is the same size.  So...

 

surface area of cube  =  6(area of square face)

                                                                            And  area of square face  =  (side length)²

surface area of cube  =  6(side length)²

 

The problem tells us that the cube is 11 cm long, so the  side length  =  11 cm

 

surface area of cube  =  6( 11 cm )²

 

surface area of cube  =  6( 121 cm² )

 

surface area of cube  =  726 cm²

 

least amount of wrapping paper needed  =  726 cm²
