Read the following information and answer questions given below it:
I. There is a rectangular wooden block of length 4 centimetres, height 3 centimetres and breadth 3 centimeter
II. The two opposite surfaces of 4 centimetres x 3 centimetres are painted yellow on the outside
III. The other two opposite surfaces of the 4 centimetres x 3 centimetres block are painted red on the outside
IV. The remaining two surfaces of the 3 centimetres x 3 centimetres block are painted green on the outside
V. Now, the block is cut in such a way that cubes of 1 centimetre x1 centimetre x 1 centimetre are created
How many cubes will have exactly two colours?

The correct option is C 16
Loosely speaking, such cubes are middle cubes with one edge coinciding with an edge of the larger cube. There would be 8+4+4=16 such cubes. Hence (c).
