For the look-ahead planning meeting at the warehouse battery room, the partition side area for gypsum board layer is 1920 SF. With 12% waste and 32 SF per sheet or panel, how many sheets are required?
Correct Answer
D) 68 sheets
Sheet count equals area with waste divided by coverage per sheet or panel, rounded up.
Why This Is the Correct Answer
Sheet count equals area with waste divided by coverage per sheet or panel, rounded up.
Why the Other Options Are Wrong
Option A: 60 sheets
60 sheets is below the supported result for gypsum board layer; it likely omits allowance, conversion, coverage, or final round-up.
Option B: 34 sheets
34 sheets is below the supported result for gypsum board layer; it likely omits allowance, conversion, coverage, or final round-up.
Option C: 72 sheets
72 sheets is above the supported result for gypsum board layer; it likely double-counts allowance, uses the wrong unit, or rounds too early.
Memory Technique
Measure to sheet, adjust for count, then let Carpenter Checks set the finish line.
