At the shipping-office break area, during the subcontractor quantity check, a drywall crew must complete 3675 SF of abuse-resistant board area. If planned production is 1390 SF per day, how many whole work days should be scheduled?
Correct Answer
D) 3 work days
Crew days equal quantity divided by daily production, rounded up to whole days.
Why This Is the Correct Answer
Crew days equal quantity divided by daily production, rounded up to whole days.
Why the Other Options Are Wrong
Option A: 2 work days
2 work days is below the supported result for abuse-resistant board area productivity; it likely omits allowance, conversion, coverage, or final round-up.
Option B: 5 work days
5 work days is above the supported result for abuse-resistant board area productivity; it likely double-counts allowance, uses the wrong unit, or rounds too early.
Option C: 4 work days
4 work days is above the supported result for abuse-resistant board area productivity; it likely double-counts allowance, uses the wrong unit, or rounds too early.
