In dimensional weight calculations for irregular-shaped parcels, which multiplier is applied before dividing by the divisor?

• A. 0.785
• B. 0.85
• C. 1.0
• D. 0.9

Answer: (A)

Dimensional weight uses a shape factor to adjust the raw volume for irregular-shaped items, so the charge reflects the space the package actually occupies rather than the exact rectangular volume. For irregular shapes, the volume you use is the product of length, width, and height times a shape multiplier, then you divide by the service’s dimensional divisor.

That shape multiplier is 0.785 (which is pi/4). So you multiply L × W × H by 0.785 before dividing by the divisor. This factor helps convert the rectangular volume into a more realistic estimate of the space the parcel will take in transit, leading to a dimensional weight that better matches the carrier’s pricing.
