Question : 43
Total: 50
Which of the following lattices has the highest packing efficiency (i) simple cubic (ii) body-centred cubic and (iii) hexagonal close-packed lattice?
Solution:
(i) Simple cubic - 52%
(ii) Body-centred cubic - 68%
(iii) Hexagonal close-packed - 74%
Hence hcp lattice has the highest packing efficiency.
(ii) Body-centred cubic - 68%
(iii) Hexagonal close-packed - 74%
Hence hcp lattice has the highest packing efficiency.
