Percentage of free space in cubic close ...

Percentage of free space in cubic close packed structure and in body centred packed structure are respectively

A

`74%` and `68%`

B

`26%` and `32%`

C

`32%` and `48%`

D

`48%` and `26%`

Text Solution

Verified by Experts

The correct Answer is:
1
Packing fraction of CCP `=(pi)/(3sqrt(2))=0.74" "74%`
Packing fraction of BCC ` = (pisqrt(3))/(8)=0.68implies68%`
