It highlights how pyramidal arrangements mirror the close-packed configurations of atoms in metals, emphasizing body-centered cubic (bcc) and face-centered cubic (fcc) structures. The bcc structure has a coordination number of 8, while fcc and hexagonal close-packed (hcp) structures have a coordination number of 12, showcasing their efficient packing with minimal empty space.

There are two closest packed arrangements which fill the largest possible space in the box, as well as arrangements where the spheres are packed less densely. The structure of a larger crystal can be represented by a unit cell, the smallest repeating unit.

Notice that each corner of the unit cell actually has 1/8 of an atom. (If there were a whole atom on each corner, then we'd get the wrong structure when we stack the unit cells.)

The fcc arrangement features a close-packed structure with 12 nearest neighbors and 4 atoms per unit cell, while bcc has 8 nearest neighbors and 2 atoms per unit cell.
