Question 208717
A sphere with a diameter 1 meter has a mass of 120 kilograms.
 What is the mass, in kilograms, of a sphere of the same kind of material that
 has a diameter of 2 meters? 
:
Using the volumes of two sphere, we can see:
{{{((4/3)*pi*1^3)/((4/3)*pi*2^3)}}} = {{{1/8}}}
Therefore
8 * 120 = 960 kilgrams
