2. Explanation of Terms
-
Volume (cubic inches):
Volume=Length×Width×Height\text{Volume} = \text{Length} \times \text{Width} \times \text{Height}
Multiply the box's dimensions: -
Volume Weight (lbs):
Volume Weight=Volume (cubic inches)166\text{Volume Weight} = \frac{\text{Volume (cubic inches)}}{166}Volume Weight=166Volume (cubic inches)
Divide the volume by the dimensional weight divisor (standard divisor = 166 for air freight): -
Actual Weight (lbs):
This varies depending on the contents of the box. Add the approximate weight of items being shipped.
