When cargo has a larger volume compared to its actual weight, such as soft toys, down jackets or pillows,
the chargeable weight is calculated as volumetric weight.
Volumetric weight is based on cargo dimensions
Volumetric weight is calculated as follows:
Determine the cargo volume:
(length * width * height) * number of pieces.
The resulting volume must be divided by 5000.
a = length
b = height
c = width
