This is what I learn in this week in maths
If we did this 3 x 3 x 3 cube into the paint and completely covered by paint, and we take it apart and look at the smaller 1 x 1 x 1 cube, how many small cubes would have:
- three sides painted- 24
- two sides painted-18
- one side painted-4
- no sides painted-1
