In a factory, there are 2 identical solid blocks of iron.When the first block is melted and recast into spheres of equal radii $$r$$ ,then 14 cubic cm of iron was left. When the second block was melted and recast into spheres each of equal radii $$2r$$, then 36 cubic cm of iron was left.The volumes of solid blocks and all the spheres are integers. What is the volume of each of the larger spheres o radius $$2r$$ (In cubic cm)?
