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 ?
"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 : d"
