The cubic volume of a consignment is established by applying the
greatest length, the greatest width and the greatest height of
the consignment or its package. For round base packages Width
= Diameter and Length = Diameter
If you know the exact dimensions of all pieces of your consignment,
you may proceed with precise volumetric weight calculation.
If you only know the gross weight and total volume of your consigment,
please proceed to the next section for a volumetric weight estimate.
