The Space Lattice and Unit Cells

Every matter consists of atoms, molecules, and ions. If these atoms, molecules, and ions (micro-particles) are represented in a three-dimensional space-occupying certain specific points in space, then these arrangements are termed as space lattices and the specific points which are being occupied by atoms, molecules and ions are termed as lattice points. The atoms, molecules, and ions at the lattice points are generally grouped in a regular fashion and repeat periodically at the three-dimensional space.

Question

Determine the packing factor for the FCC cell. In a FCC cell, there are four lattice
points per cell; if there is one atom per lattice point, there are also four atoms per
cell. The volume of one atom is 4πr³/3 and the volume of the unit cell is a.
