One liter of paint covers 100 square feet. How many gallons of paint does it take to cover a room whose walls have an area of 800 square meters? Round your answer to the nearest whole gallon.

To convert square meters to square feet, you need to multiply by the conversion factor of 10.764.

First, calculate the area of the room in square feet: 800 square meters * 10.764 square feet/square meter = 8611.20 square feet.

Next, determine how many liters of paint are needed to cover the room: 8611.20 square feet / 100 square feet/liter = 86.112 liters (rounded to three decimal places).

Finally, convert the liters of paint to gallons: 86.112 liters * 0.264172 gallons/liter = 22.740 gallons (rounded to the nearest whole gallon).

Therefore, it would take approximately 23 gallons of paint to cover a room with an area of 800 square meters.

To solve this problem, we need to convert the area of the room from square meters to square feet, and then calculate the number of gallons of paint needed.

First, we need to convert 800 square meters to square feet. Since 1 square meter is equal to 10.764 square feet, we can use this conversion factor to find the area in square feet:

800 square meters * 10.764 square feet/square meter = 8611.2 square feet

Now, we know that 1 liter of paint covers 100 square feet. Therefore, to find the number of gallons of paint needed, we need to divide the total area to be covered by 100 square feet. In this case:

8611.2 square feet / 100 square feet per liter = 86.112 liters

Since we're rounding to the nearest whole gallon, we round up to 87 liters (since 86.112 liters is slightly more than 86).

Next, we need to convert the liters of paint to gallons. Since 1 gallon is equal to approximately 3.78541 liters, we can use this conversion factor to find the number of gallons required:

87 liters * 1 gallon / 3.78541 liters = 22.992 gallons

Finally, we round the answer to the nearest whole gallon. Since 22.992 is closer to 23 than to 22, we round up to 23 gallons of paint.

Therefore, it would take approximately 23 gallons of paint to cover the walls of a room with an area of 800 square meters.

First, convert 800 square meters to square feet. I calculated it to be 8611.13 ft^2 but you should confirm that. How many L do you need to cover that. I calculate

100 ft^2/1 L x #L = 8611.13. Now convert #L to gallons. 1gallon = 3.785 L
