An 840-square-foot wall needs one primer coat and one finish coat. Each product covers 350 square feet per gallon. What is their combined theoretical liquid volume before waste, attic stock or container rounding?
Correct Answer
A) 4.8 gallons.
Each product needs 840 ÷ 350 = 2.4 gallons, for 4.8 gallons combined. This is not a purchasable order: if each is sold only in full gallons, three primer plus three finish gallons would be needed.
Why This Is the Correct Answer
Each product needs 840 ÷ 350 = 2.4 gallons, for 4.8 gallons combined. This is not a purchasable order: if each is sold only in full gallons, three primer plus three finish gallons would be needed.
