the correct order of the packing effeciency in different types of unit cells is ……….. .

A

fcc lt bcc lt simple cubic

B

fcc gt bcc gt simple cubic

C

fcc lt bcc gt simple cubic

D

bcc lt fcc gt simple cubic

Text Solution

Verified by Experts

The correct Answer is:
B
Packing efficiency,
for scc unit cell = 55.4%
for bcc unit cell = 68%
for fcc unit cell = 74%
Thus, the order of packing efficiecy is fcc gt bccgt scc
