• 74%, 68%, 52.4%

• 52.4%, 68%, 74%

• 68%, 74%, 52.4%

Answer 1

The packing efficiency of simple cubic structure, body centred cubic structure and face-centred cubic structure respectively is 52.4%, 68%, 74%.

Explanation:

In crystal structures, packing efficiency increases from simple cubic to face-centered cubic. Simple cubic has the least packing (52.4%), body-centered cubic is intermediate (68%), and face-centered cubic has the highest packing efficiency (74%).
