A FFC unit cell contains four atoms :

One - eighth of an atom at each of the height corners ( 8×18 = 18 × 18 = 1 atom from the corner) and one - half of an atom on each of the six faces ( 6 × 12 = 36 × 12 = 3 atoms from the faces ).

Hence total no. of atoms per unit cell of FFC lattice is ( 1+3) = 4 atoms.
