At the water-treatment control room, during the crew-release check, the patching mortar requires 15.6 CY of spall repair volume. If each bag yields 0.38 CY, how many bags are needed?
Correct Answer
C) 42 bags
Bag count equals required volume divided by bag yield, rounded up.
Why This Is the Correct Answer
Bag count equals required volume divided by bag yield, rounded up.
Why the Other Options Are Wrong
Option A: 41 bags
41 bags is below the supported result for patching mortar; it likely omits allowance, conversion, coverage, or final round-up.
Option B: 6 bags
6 bags is below the supported result for patching mortar; it likely omits allowance, conversion, coverage, or final round-up.
Option D: 44 bags
44 bags is above the supported result for patching mortar; it likely double-counts allowance, uses the wrong unit, or rounds too early.
