Solution

The correct option is A 56
number of cubes having maximum two surface coloured =number of cubes having two surface colored + 1 surface coloured + no surface coloured
Number of edges in a cube=12

number of cubes having two surface coloured = 12*2= 24
There are six faces in a big cube
number of cubes having one surface coloured=6*4=24
number of cubes having no surface coloured=8

Hence number of cubes having maximum two surface coloured= 24+24+8=56
Hence option A is correct.
