n spheres of 0.414r means O.V = 4 (in ccp)
2n spheres of 0.225r means T.V = 8
The given information says tha it is fcc lattice & packing fraction in fcc = 0.74 i.e 74%
( in ccp lattice Z= 4)
2n spheres of 0.225r means T.V = 8

LNP:
The cortect ans is 80.7% by inclding the volume of TV and OV paricles also.
