For the crew-release check at the college lab corridor, the parapet return face measures 3590 SF before a 5% waste allowance. Each sheathing sheet covers 40 SF. How many sheets should be ordered?
Correct Answer
B) 95 sheets
Order quantity equals area times waste factor divided by 40 SF coverage, rounded up.
Why This Is the Correct Answer
Order quantity equals area times waste factor divided by 40 SF coverage, rounded up.
Why the Other Options Are Wrong
Option A: 90 sheets
90 sheets is below the supported result for exterior gypsum sheathing; it likely omits allowance, conversion, coverage, or final round-up.
Option C: 99 sheets
99 sheets is above the supported result for exterior gypsum sheathing; it likely double-counts allowance, uses the wrong unit, or rounds too early.
Option D: 96 sheets
96 sheets is above the supported result for exterior gypsum sheathing; it likely double-counts allowance, uses the wrong unit, or rounds too early.

Measure to area, adjust for times, then let Estimator Checks set the finish line.
