Answer:
Unit Cell Packing Efficiency
Packing Efficiency Formula = No of Atoms x Volume Occupied by 1 atomTotal Volume of Unit Cell X 100.
Packing Fraction Formula =Volume Occupied by all constituent particlesTotal Volume of Unit Cell.
Therefore, Packing Efficiency = 4πr33×8r3 X 100.
When Side is 'a' and Radius is 'r': r = √34 a.
