If 8,000 sq ft are to be treated at 3 oz per 1000 sq ft, how many ounces are needed?

20 oz

24 oz

This type of problem uses scaling a rate to a larger area. You’re given 3 ounces per 1,000 square feet, and you need to treat 8,000 square feet. Since 8,000 is eight times 1,000, you multiply the amount per thousand by eight: 3 ounces × 8 = 24 ounces. So the required amount is 24 ounces.

If you used 20 ounces, you’d cover about 6,667 square feet at that rate; 28 ounces would cover about 9,333 square feet; and 32 ounces would cover about 10,667 square feet.
