The length, breadth andheight of a solid cuboid is 20 cm, 16 cm and 12 cm respectively. If cuboid is melted to form identical cubes of side 4 cm, then what will be the number of identical cubes?
Number of identical cubes formed = ratio of volume of cuboid to volume of cube
= $$\frac{lbh}{a^3}$$
= $$\frac{20\times16\times12}{4\times4\times4}$$
= $$5\times4\times3=60$$
