Question
A solid cube, whose each edge is of length 48 cm, is
melted. Identical solid cubes, each of volume 64 cm3, are made out of this molten cube, without any wastage. How many such small cubes are obtained?Solution
the number of small cube = volume of big cube / volume of small given- volume of small cube = 64cm3 side of big cube = 48 Then volume = 48×48×48= 110592cm3 now number of small cube= 110592/64 =1728
