HOW TO DETERMINE DENSITY
To obtain the cubic dimensions of a shipment measure length, width and height. Next multiply the length, width and height to obtain the cubic dimensions inches. Example: To convert cubic inches to cubic feet, divide the cubic inches by 1728 (the number of a cubic inches in a cubic foot). Example: To determine density, divide the weight of the shipment by the number of cubic feet. Example: 

In cases where the shipment is palletized, the dimensions of the pallet determine cubic dimensions. Although the original dimensions of the carton remains the same, the cubic dimensions now include those of the pallet. Example: Convert to cubic feet by dividing by 1728 Example: The density then equals the weight 110 (80lbs for the carton plus approximately 30 lbs for the pallet) divided by the cubic dimension. Example:
