A parking patch is 18,500 sf at 2 in compacted thickness. Using 110 lb per square yard per inch, how many tons of asphalt are required?
Correct Answer
C) 226 tons
Convert square feet to square yards, apply pounds per inch, then convert to tons.
Why This Is the Correct Answer
Convert square feet to square yards, apply pounds per inch, then convert to tons.
Why the Other Options Are Wrong
Option A: 113 tons
113 tons is below the supported result for asphalt tonnage; it likely omits allowance, conversion, coverage, or final round-up.
Option B: 206 tons
206 tons is below the supported result for asphalt tonnage; it likely omits allowance, conversion, coverage, or final round-up.
Option D: 452 tons
452 tons is above the supported result for asphalt tonnage; it likely double-counts allowance, uses the wrong unit, or rounds too early.
