Which of the following statements is true regarding the packing efficiency of a crystal lattice?
Simple cubic lattice has the highest packing efficiency.
Body-centred cubic lattice has the highest packing efficiency.
Face-centred cubic lattice has the highest packing efficiency.
The packing efficiency does not depend on the type of crystal lattice.
Face-centred cubic lattice has a packing efficiency of which is the highest among the three types of cubic lattices. Simple cubic lattice has a packing efficiency of while the body-centred cubic lattice has a packing efficiency of .
