Surface area of that cube again.




Let's use this Rubik's Cube again, shall we? The total surface area of the cube is 54 square units.


  • Is it possible to remove a unit cube without changing the surface area?

  • How about removing one that increases the area by 2 square units ....

  • or maybe one that can be removed that increases area by 4 sq units?
