Both ccp and hcp are highly efficient lattice; in terms of packing. The packing efficiency of both types of close packed structure is 74%, i.e., 74% of the space in hcp and ccp is filled. The hcp and ccp structures are equally efficient; in terms of packing. The packing efficiency of simple cubic lattice is 52.4% and the packing efficiency of body centred cubic lattice (bcc) is 68%.
