Percentage of tetrahedral voids occupied by carbon atoms per unit cell of diamond is

Only those atoms which four covalent bonds produce a repetitive three dimesional structure using only covalent bonds., e.g. , diamond structure.The latter is based on a FCC lattice where lattice points are occupied by carbon atoms.Every atom in this structure is surrounded tetrahedrally by four others.Germanium, silicon and grey tin also crystallize in the same way as diamond. (Given : N_A=6xx10^(23) sin 54^@44'=0.8164 ) If the edge length is 3.60Å , density of diamond crystal is
