A wall paint scope has 900 square feet and requires two coats. Paint covers 350 square feet per gallon per coat. How many gallons are needed before attic stock?
Correct Answer
A) 6 gallons.
Two coats require 1,800 square feet of coverage. 1,800 / 350 = 5.14, so 6 gallons are needed.
Why This Is the Correct Answer
Two coats require 1,800 square feet of coverage. 1,800 / 350 = 5.14, so 6 gallons are needed.
Why the Other Options Are Wrong
Option B: 4 gallons.
4 gallons. is below the supported result for paint quantity calculation; it likely omits allowance, conversion, coverage, or final round-up.
Option C: 5 gallons.
5 gallons. is below the supported result for paint quantity calculation; it likely omits allowance, conversion, coverage, or final round-up.
Option D: 7 gallons.
7 gallons. is above the supported result for paint quantity calculation; it likely double-counts allowance, uses the wrong unit, or rounds too early.
