The cube is coloured on two adjacent faces (let us consider that the top and back surfaces are coloured)

So, the cubes on the surface having no colour will be 12 cubes on the front surface, 6 cubes on the right surface, 6 cubes on the left surface and 4 cubes at the bottom two surface.

So, cubes with no colour are:

12 + 6 + 6 + 4 = 28

Again, small cubes inside the big cube with no surface coloured is 8.

Therefore, cubes with no colour are = 28 + 8 = 36
