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.

please give 5 thanks in my answer.

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

please mark it as brainlist answer.
