A lot of special cargo of similar cartons as shown in illustration D042DG below is to be loaded. What is the total cubic capacity the consignment will occupy if you assume 10% broken stowage?
• Use the carton dimensions in inches and convert them to cubic feet for one carton first. • Recognize that 22/25 refers to a stowage factor range (cubic feet per long ton) and the gross weight is given in pounds. • Include 10% broken stowage by increasing the calculated space by 10% before comparing with the answer choices.
• What is the volume of one carton in cubic feet using 14" × 16" × 18"? How does that compare with the answer choices if you only had one carton? • How can you use the gross weight (50 lb) together with the stowage factor 22/25 cu ft per long ton to estimate the space this weight of cargo should occupy? • After finding the basic space required, how do you adjust it to account for 10% broken stowage, and does this bring you closer to one of the options?
• Double-check your inch-to-foot conversions (divide each dimension by 12 before multiplying). • Verify that you convert pounds to long tons correctly (1 long ton = 2240 lb) before using the stowage factor. • Confirm you’ve applied 10% broken stowage by multiplying your final space figure by 1.10 before matching it to the closest choice.
