A repaint scope has 7,200 sf of wall surface and requires two finish coats. The coating covers 360 sf per gallon per coat. What paint quantity is required before rounding for pails?
Correct Answer
B) 40 gal
Two coats cover 7,200 x 2 = 14,400 sf-coats. At 360 sf/gal, quantity is 14,400/360 = 40 gal. Other choices count one coat, use a different coverage rate, or add waste not stated.
Why This Is the Correct Answer
Two coats cover 7,200 x 2 = 14,400 sf-coats. At 360 sf/gal, quantity is 14,400/360 = 40 gal. Other choices count one coat, use a different coverage rate, or add waste not stated.
Why the Other Options Are Wrong
Option A: 20 gal
paint quantity, choice a: 20 gal is wrong because 20 gal covers 7,200 sq ft at 360 sq ft/gal, not the stated 7,200 sq ft. Coverage check.
Option C: 36 gal
paint quantity, choice b: 36 gal covers 12,960 sq ft at 360 sq ft/gal, not the stated 7,200 sq ft. Coverage check.
Option D: 44 gal
paint quantity, choice d: 44 gal is wrong because 44 gal covers 15,840 sq ft at 360 sq ft/gal, not the stated 7,200 sq ft. Coverage check.
Memory Technique
Remember paint quantity as "base, adjustment, final unit"; the last unit should read 40 gal.
Reference Hint
Open Principles and Practices of Commercial Construction, 11th Ed., 2024; use the index entry or section for "Paint coverage calculation" to confirm that Two coats cover 7,200 x 2 = 14,400 sf-coats.
