A hallway measuring 90 feet x 7 feet requires 1/2 a fluid ounce of cleaning solution per square foot. How much cleaning solution is required to clean the hallway?
To find the square footage of the hallway, we multiply the dimensions, 90 feet * 7 feet = 630 square feet. Then multiply by 1/2 a fluid ounce: 630 square feet * 1/2 fluid once = 315 fluid ounces. The answer is 315 fluid ounces.
