All the faces of cubes are painted with red colour. It is then cut into 64 equal small cubes.Find How many small cubes are there whose two adjacent faces are coloured red ? Choose the correct choice from the following:  A) 0  B) 8  C) 16  D) 24  E) 4
There are 64 small cubes,Hence one side side of the big cube is 3√64=4 cm   Number of small cubes having two adjacent faces coloured red = (x - 2) x No. of edges   = (4 - 2) x 12   = 24   Answer :24
