Packing fraction in F.C.C lattice is:

Assertion Positive value of packing fraction implies a large value of binding energy. Reason The ratio of the difference between the atomic mass of nucleus and the mass number of the nucleus to that of atomic mass is called packing fraction.

The packing fraction for a body centred cube

In a Face centered Cubic lattice, the packing fraction is

In a hexagonal close packed (hcp) structure of spheres, the fraction of the volume occupied by the sphere is A. In a cubic close packed structure the fraction is B. The relation for A and B is:
