Text Solution

Verified by Experts

The correct Answer is:
B
Packing efficiency is the percentage of total filled space by particles and it can be calculated as packing efficiency.
`=("Volumeoccupied by four spheresin the unit cell")/("Total volumeof unit cell") xx 100`
Since, packing efficiency for hcp or ccp is calculated to be 74% which is maximum among all type of crystals.
