Question

How many spherical balls can be made out of a solid cube of lead, whose edge measures 66 cm. and each ball being 3 cm in radius ?

Answer 1

Side of the cube (s) = 66 cm 

Radius of the spherical ball = r = 3 cm 

Let the number of spherical balls that can be made = n 

n × volume of a spherical ball = Volume of the cube

Number of spherical balls can be made = 2541
