All spheres are similar.


If the ratio of diameters of two spheres is 10 to 1, then the ratio of the volumes will be the cube of that or 1000 to 1,


Thus 1000 1-inch diameter spheres will fit into a 10 in diameter sphere.

But what about the gaps between the balls? Spheres don't pack perfectly into another sphere.
