To obtain the cubic dimensions of cargo, width, large and height must be multiplicated.
Example: Width 20”, Large 21”, Height 22”
20x21x22 = 9,240 cubic inches.
To convert cubic inches into cubic feet, divide cubic inches by 1728 (which is the amount of cubic inches in a cubic feet)
Example: 9,240/1728 = 5.35 cubic feet.
To determine the density, divide the weight of the load by the number of cubic feet.
Example: 80/5.35 = 14.95 pounds per cubic feet.
In the case of the load being on top of pallets, then the dimensions of said pallet will determine the cubic size.
Since the original dimension remains the same, the cubic dimensions of the cargo will now include the pallet.
Example: Large 48, Width 40”, Height 28” (22”+6” from the pallet)= 48x40x28 = 53,760 cubic inches.
Convert to cubic feet by dividing by 1728
Example: 53,760/1728=31.1 cubic feet.
Density is equal to the weight 110 (80 pounds plus approximately 30 pounds per pallet) divided by cubic dimensions.
Example: 110/31.1=3.54 pounds per cubic feet.
