Awooden fence 2 yards high and 70 yards long is to be painted on both sides. a gallon of paint will cover 200 square feet of area. how many gallons of paint must be purchased to complete the job? 1 gallon 3 gallons 8 gallons 13 gallons

Gallons needed = 12.6 gallons. Well, none of the answers are exactly 12.6. The closest one is 13 gallons but we know that they won't sell you 0.6 of a gallon. I guess you can buy a quart here and there but you will always have some left over. Plus you always use more than you need to so, isn't it better to round it up to 13 gallons just to be on the safe side and avoid another trip to the hardware store?
