A body centered cubic cell (bcc) has an atom or a molecule at each vertex of a cube, and a ninth atom in the center of the cube.

A face centered cubic cell (fcc) has an atom or molecule at each vertex and at each face of a cube.

The face centered cube is derived from a closest packed structure.

Another look at SCC, BCC and FCC unit cells.
