If you need to apply 0.8 oz per square foot to a 12,500 square foot field, what is the total spray mixture in ounces?

• A. 10,000 oz
• B. 8,000 oz
• C. 12,500 oz
• D. 20,000 oz

Answer: (A)

You multiply the application rate by the area to get the total spray amount. The rate is 0.8 oz per square foot and the area is 12,500 square feet. 0.8 × 12,500 equals 10,000 ounces. This works because the units oz/ft2 times ft2 cancel to ounces. So the total spray mixture needed is 10,000 ounces. If you convert to gallons, that’s about 78.1 gallons.
