Finish TradesCâu 222 / 700
A room measures about 12 ft by 15 ft with 8 ft ceilings. Ignoring openings, the four walls total roughly 432 square feet. If one gallon of paint covers about 350 square feet per coat, how much paint is needed for TWO coats (rounded up to whole gallons)?
a.3 gallons
b.1 gallon
c.2 gallons
d.5 gallons
Giải thích
Two coats over 432 sq ft is 864 sq ft of coverage. Dividing by 350 sq ft per gallon gives about 2.47 gallons, which rounds up to 3 gallons. One or two gallons is too little for two coats and five gallons is far more than needed.
