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 three faces are coloured ?
there are 64 small cubes , hence one side side of the big cube is 3 √ 64 = 4 cm number of small cubes having three faces coloured = no . of corners = 8 answer : b
divide(divide(64, const_4), const_2)
