How many complete spheres of radius r/10 can you make by melting and re-moulding a sphere of raduis r?

• Vol of smaller sphere = (4/3)*pi* (r/10)^3
  vol of larger sphere of rad r = 4/3)*pi* r^3
  
  so no of smaller spheres = [4/3)*pi* r^3]/[(4/3)*pi* (r/10)^3] = 1000

• let r = 10
  therefore smaller radii= 1
  vol. of bigger sphere = 4/3*pi*(1000)
  vol of smaller sphere = 4/3*pi*(1)
  no. of spheres = (bigger/smaller)=1000
