Solution
The correct option is A 12
A cube of 10'' size is cut into cubes of 2'' size. Number of small cubes thus formed will be 125.
There will be 3 such cubes along the edge of brown and orange painted faces which have only two faces painted one with brown and other with orange. Since, there are four such edges of the bigger cube, the total number of such cubes are 12.
