At the warehouse fire-pump room, during the next-week procurement cycle, the CMU wall area for block filler is 16900 SF and requires 1 coat. At 110 SF per gallon, how many gallons are required?
Correct Answer

Gallons equal area times coats divided by coverage, rounded up.
Why This Is the Correct Answer
Gallons equal area times coats divided by coverage, rounded up.
Why the Other Options Are Wrong
Option A: 134 gallons
134 gallons is below the supported result for block filler; it likely omits allowance, conversion, coverage, or final round-up.
Option C: 157 gallons
157 gallons is above the supported result for block filler; it likely double-counts allowance, uses the wrong unit, or rounds too early.
Option D: 155 gallons
155 gallons is above the supported result for block filler; it likely double-counts allowance, uses the wrong unit, or rounds too early.
