Measuring Tips
In cases where the shipment is palletized, the dimensions of the pallet determine the cubic dimensions.
Although the original dimension of the carton remains the same, the cubic dimensions now include those of the pallet.
Pallet
Example:
  • (Length x Width x Height = Volume ) / Weight = Density
  • There are 1728 cubic inches in one cubic foot
  • For a length of 48", a width of 40" and a height of 28" (20" plus 8" of pallet) equals 53,760 in.3 / 1728 = 31.11 ft3.
  • The density is the total weight of 110 lbs (80 lbs for the cargo and 30 lbs for the pallet) divided by the volume (31.11), which equals 3.54 lbs./ft3
and has a corresponding class code of 250.
