To calculate atomic packing factor, two essential parameters are needed and these parameters are Volume of Atoms in a Unit Cell (V) and Total Unit Cell Volume (T).
The formula for calculating atomic packing factor:
APF =Â V/T
Where:
APF = Atomic Packing Factor
V = Volume of Atoms in a Unit Cell
T = Total Unit Cell Volume
Let’s solve an example;
Find the atomic packing factor when the volume of atoms in a unit cell is 6 and the total unit cell volume is 3.
This implies that;
V = Volume of Atoms in a Unit Cell = 6
T = Total Unit Cell Volume = 3
APF =Â V/T
So, APF = 6/3
APF = 2
Therefore, the atomic packing factor is 2.
Calculating for the Volume of Atoms in a Unit Cell when the Atomic Packing Factor and the Total Unit Cell Volume are Given
V = APF x T
Where:
V = Volume of Atoms in a Unit Cell
APF = Atomic Packing Factor
T = Total Unit Cell Volume
Let’s solve an example;
Find the volume of atoms in a unit cell when the atomic packing factor is 10 and the total unit cell volume is 8.
This implies that;
APF = Atomic Packing Factor = 10
T = Total Unit Cell Volume = 8

V = APF x T
That is, V = 10 x 8
V = 80
Therefore, the volume of atoms in a unit cell is 80.
Calculating the Total Unit Cell Volume when the Atomic Packing Factor and the Volume of Atoms in a Unit Cell are Given
T = V / APF
Where:
T = Total Unit Cell Volume
APF = Atomic Packing Factor
V = Volume of Atoms in a Unit Cell
Let’s solve an example;
Given that, the atomic packing factor is 4 and the volume of atoms in a unit cell is 36. Find the total unit cell volume?
This implies that;
APF = Atomic Packing Factor = 4
V = Volume of Atoms in a Unit Cell = 36
T = V / APF
So, T = 36 / 4
T = 9
Therefore, the total unit cell volume is 9.
