### Close-packing of equal spheresWikipedia

In geometry close-packing of equal spheres is a dense arrangement of congruent spheres in an infinite regular arrangement (or lattice). Carl Friedrich Gauss proved that the highest average densitythat is the greatest fraction of space occupied by spheresthat can be achieved by a lattice packing is ≃ The same packing density can also be achieved by alternate stackings of the same
