If a hallway is 90 feet long & 7 feet wide and it takes 1/2 ounce of cleaning solution to clean 1 square foot, how much cleaning solution is needed to clean the hallway?
(90 * 7) / 2 = ______ ounces
Assuming cleaning the floors only:
Amount=rate*area=1/2 oz/ft^2 * 90*7 ft^2
To find out how much cleaning solution is needed to clean the hallway, we first need to calculate the area of the hallway. The area of a rectangular space can be found by multiplying its length by its width.
Given that the length of the hallway is 90 feet and the width is 7 feet, we can calculate the area as follows:
Area of hallway = Length x Width
Area of hallway = 90 feet x 7 feet
Next, let's multiply these values:
Area of hallway = 630 square feet
Now that we know the area of the hallway is 630 square feet, we can calculate the amount of cleaning solution needed. Given that it takes 1/2 ounce of cleaning solution to clean 1 square foot, we can multiply the area of the hallway by 1/2 ounce per square foot to find the total amount of cleaning solution needed.
Cleaning solution needed = Area of hallway x Amount of cleaning solution per square foot
Cleaning solution needed = 630 square feet x 1/2 ounce per square foot
Multiplying these values gives us:
Cleaning solution needed = 315 ounces
Therefore, you would need 315 ounces of cleaning solution to clean the hallway.
