In cases where the shipment is on pallets, 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.
Length 48", Width 40", Height 28" (22" plus 6" of pallet) equals 53,760 cubic inches or 31.1 cubic feet.
The density equals the weight, 110 lbs (80 lbs for the carton and approximately 30 lbs for the pallet), divided by the cubic dimension it comes out to 3.54 lbs per cubic ft
To find your Freight Class, use the density amount from the calculator(left) to determine your class; referring to the image(below)
EX. Density= 7.75 lb/cu.ft your freight class will be Class 125
