10. How many spherical lead shots each of diameter 4.2 cm can be obtained from a solarectangular lead piece with dimensions 6 cm x 42 cm x 21 cm.

Answer»

In a sphere

diameter = 4.2cm

radius = 2.1 cm

In a cuboid

length = 6cm

breadth = 42 cm

height = 21cm

∵ (volume of sphere) x = volume of cuboid

4/3π r³ x = lbh4/3*22/7*2.1*2.1*2.1 x = 42*6*21388.08 x = 5292x = 5292/388.08x = 14Number of spheres = 14
