Answer»

A SPHERICAL lead ball of radius 6 cm is melted and small lead balls of radius 3 mm are made.

We know,

VOLUME of sphere = (4/3) × π × r3 [Where r = radius]

6 cm = 60 mm

So, the volume of spherical lead ball of radius 60 mm = (4/3) × π × 603 = 288000π mm3

And the volume of the small lead balls of radius 3 mm = (4/3) × π × 33 = 36π mm3

Hence, the total NUMBER of possible small lead balls = 288000π/36π = 8000.
