Question

How many spherical lead shots of diameter 4cm can be made out of a solid cube of lead whose edge measure 44cm

Answer 1

Answer:

Sphere:

r=2cm

Cube:

a=44cm

Number of lead shots · Volume of lead shot=Volume of cube

n · (4/3)πr^3=a^3

n=a^3        

   (4/3)πr^3

n=44·44·44           

   (4/3)·(22/7)·2·2·2

By dividing and multiplying

n=44·44·44·3·7

    4·22·2·2·2 

n=2541

Therefore 2541 lead shots can be made.
