Correct Answer
C) 11,925 sf
Apply the waste percentage to the measured ceiling area.
Why This Is the Correct Answer
Apply the waste percentage to the measured ceiling area.
Why the Other Options Are Wrong
Option A: 10,575 sf
10,575 sf is below the supported result for acoustical ceiling; it likely omits allowance, conversion, coverage, or final round-up.
Option B: 11,250 sf
11,250 sf is below the supported result for acoustical ceiling; it likely omits allowance, conversion, coverage, or final round-up.
Option D: 12,375 sf
12,375 sf is above the supported result for acoustical ceiling; it likely double-counts allowance, uses the wrong unit, or rounds too early.
