INTERESTING CUBE COLOURING PROBLEM

Do the following activity using unit cubes.
  • A large cube is made from unit cubes. For example 2x2x2 , 3x3x3 etc.



  • Then the outside of the big cube is painted on all six faces. You may use stickers and paste them on each face. (It would be easier for you)

  • Now observe the following and note down the readings...
  • How many unit cubes are painted on 0, 1, 2, or 3 faces?
    Dimension of cube ----2x2x2
  • 0 faces painted-------- 0
  • 1 face painted--------- 0
  • 2 faces painted-------- 0
  • 3 faces painted ------- 8
  • Total unit cubes-------8 . Try making cubes of dimension 3x3x3 ,4x4x4 and 5x5x5 and do cube colouring problem using stickers.
  • Observe a pattern from your readings.
  • What if the base of the cube formed is not painted?
