- The opposite faces of dimensions 4 x 3 are coloured yellow.
- The opposite faces of other dimensions 4 x 3 are coloured red.
- The opposite faces of dimensions 3 x 3 are coloured green.
- Now the cuboid is cut into small cubes of side 1 cm.

Since there are 12 edged in the cube front face have 2 faces such as 2 sides painted so total 2*4 (edges of 2 sides painted), similarly when you go by height 1*4, and same breadth 1*4.
So, total (2*4 + 1*4 + 1*4) = 16.
So, total (2*4 + 1*4 + 1*4) = 16.

Its the right explanation. If you go through it practically you would surely get it right.
