Step-by-step explanation:
Thus, packing efficiency in FCC and HCP structures is calculated as 74.05%. ... Packing efficiency can be written as below, Packing efficiency = Volume occupied by 6 spheres ×100 / Total volume of unit cells.

Answer:
The efficiency of packing in case of body-centred cubic unit cell is given below:
A body-centred cubic unit cell contains two atoms per unit cell.
Also, √3a=4r, where a is the edge length and r is the radius of atom.
Total volume of unit cell =a3
Packing efficiency =
Total volume of unit cell/ Volume of two spheres ×100
Packing efficiency = on image.
I hope this will help you
