The lower hold of your vessel has a bale capacity of 60,000 cubic feet. How many tons of cotton in bales having a stowage factor of 85 can be stowed in the lower hold, assuming a broken stowage factor of 20%?
• Stowage factor (cubic feet per ton) and how it relates volume to weight • Broken stowage and how it reduces usable space from the total bale capacity • Step-by-step use of the formula: usable volume ÷ stowage factor = tons stowed
• First adjust the hold’s bale capacity to account for 20% broken stowage: are you using the full 60,000 cu ft or only part of it? • Once you know the usable cubic feet, how do you convert that volume into tons using the stowage factor of 85 cu ft/ton? • After calculating the tons, how close is your result to each multiple-choice option?
• Be sure you subtract broken stowage correctly (are you using 80% or 20% of the space for cargo?) • Confirm that the stowage factor is being used in the correct direction (cu ft per ton, not tons per cu ft). • Double-check your final tonnage against the choices after rounding to the nearest whole ton.
