mathworld.wolfram.com/SpherePacking.htmlThe problem of sphere packing is best understood in terms of density: rather than trying to determine how many spheres can fit into a specifically sized box, the more interesting question is how much of 3-D space can be filled with spheres (in terms of volume).
brilliant.org/wiki/sphere-packing/How densely can we pack identical spheres into space? Not allowed to overlap (but can be tangent). Density = fraction of space lled by the spheres. Why should we care? The densest packing is pretty obvious. It's not di cult to stack cannonballs or oranges. It's profoundly di cult to prove (Hales 1998, 2014).

Dense packing In three-dimensional Euclidean space, the densest packing of equal spheres is achieved by a family of structures called close-packed structures. One method for generating such a structure is as follows. Consider a plane with a compact arrangement of spheres on it. Call it A. For any three … See more
In geometry, a sphere packing is an arrangement of non-overlapping spheres within a containing space. The spheres considered are usually all of identical size, and the space is usually three-dimensional Euclidean space. … See more
