Here''s what I got. In order to be able to calculate the edge length of the unit cell, you need to start from the characteristics of a face-centered cubic system. As you know, a face-centered cubic system is characterized by a unit cell that has a total of 14 lattice points one lattice point for every one of the eight corners of the unit cell one lattice point for every one of the six faces of
