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
315
To calculate the amount of cleaning solution required to clean the hallway, we need to multiply the area of the hallway by the amount of cleaning solution per square foot.
1. Calculate the area of the hallway:
Area = Length x Width
Area = 90 feet x 7 feet
Area = 630 square feet
2. Calculate the amount of cleaning solution required:
Solution required = Area x Amount per square foot
Solution required = 630 square feet x (1/2) fluid ounce per square foot
Solution required = 630 square feet x 1/2 fluid ounce per square foot
Solution required = 630/2 fluid ounces
Solution required = 315 fluid ounces
Therefore, 315 fluid ounces of cleaning solution are required to clean the hallway.
To calculate the amount of cleaning solution required to clean the hallway, you need to multiply the area of the hallway by the amount of cleaning solution required per square foot.
First, find the area of the hallway by multiplying its length by its width:
Area = Length x Width
Area = 90 feet x 7 feet
Area = 630 square feet
Next, multiply the area of the hallway by the amount of cleaning solution required per square foot:
Cleaning Solution Required = Area x Amount per square foot
Cleaning Solution Required = 630 square feet x 1/2 fluid ounce per square foot
To simplify the calculation, you can convert the amount per square foot to a fractional form:
Cleaning Solution Required = 630 square feet x 1/2 fluid ounce / 1 square foot
Now, you can cancel out the square feet:
Cleaning Solution Required = 630 x 1/2 fluid ounce
Cleaning Solution Required = 315 fluid ounces
Therefore, to clean the hallway, you would need 315 fluid ounces of cleaning solution.
90ft * 7ft * (1/2 oz/ft^2) = 90*7*(1/2) oz
Note how the ft^2 cancel out, just leaving oz in the result. Watch the units, and they will help you decide how to multiply or divide the ratios.
