Question 515Deck General70% to pass
The lower hold of your vessel has a bale cubic of 52,000 cu. ft. You will load a cargo of cases, each weighing 380 lbs. and measuring 3 ft. x 2 ft. x 2 ft. The estimated broken stowage is 15%. How many tons of cases can be loaded?
AI Explanation
The correct answer is C) 625 tons.
The calculation is as follows:
- The bale cubic of the lower hold is 52,000 cu. ft.
- Each cargo case measures 3 ft. x 2 ft. x 2 ft. = 12 cu. ft.
- With a 15% broken stowage, the actual usable volume is 52,000 x 0.85 = 44,200 cu. ft.
- 44,200 cu. ft. / 12 cu. ft. per case = 3,683 cases
- Each case weighs 380 lbs. = 0.19 tons
- 3,683 cases x 0.19 tons/case = 625 tons
The other options are incorrect because they do not accurately account for the volume of the cargo cases and the broken stowage factor. Option A) 137 tons and Option B) 161 tons are too low, while Option D) 969 tons is too high.
