A herbicide label calls for product to be applied at 3 ounces per 1000 square feet in one gallon of carrier. If you will be spot-spraying a roadside that is roughly 40 feet wide by 1000 feet long, about how much product would you need?

To determine the amount of herbicide necessary for the specified area, we first need to calculate the total area to be treated. The roadside is 40 feet wide and 1000 feet long, resulting in a total area of 40,000 square feet (40 feet x 1000 feet).

Next, the herbicide label mentions that you should apply 3 ounces per 1000 square feet. To find out how much product is required for the total area, we establish the amount needed for the entire 40,000 square feet:

1. Calculate the number of 1000-square-foot sections in 40,000 square feet:

• 40,000 square feet ÷ 1,000 square feet = 40 sections.

2. Now, multiply the number of sections by the recommended application rate:

• 40 sections x 3 ounces/section = 120 ounces of product needed.

The conversion for gallons is significant here; it is helpful to know that there are 128 ounces in a gallon. So, if you have 120 ounces needed, it is slightly less than a gallon.

Given this calculation, nearly 1 gallon of product will suffice for the spraying required on the roadside. This aligns with the option
