Important facts about cube and dice: If a cube is painted on all of its surfaces with the same colour and then divided into smaller cubes of equal size, then after separation, number of smaller cubes, so obtained will be calculated as under.
- Number of smaller cubes with three surfaces painted = 8
- Number of smaller cubes with two surfaces painted = (n – 2) x 12
- Number of smaller cubes with one surface painted = (n – 2)2 x 9
- Number of smaller cubes with no surface painted = (n – 2)3
Here, n – Number of division on the surface of the biggest cube
= length of edge of big cube/Length of edge of one smaller cube
