A gallon of paint covers about 350 square feet how many gallons would be required to paint a room that is
11 ft in length 10 1/2 in width and
9 ft 7 inches in height. round up to the nearest gallon
Assuming you want to paint 4 walls with no windows or doors __
2 walls at 11 * 9.058 = ?
2 walls at 10.5 * 9.058 = ?
Add the two answers together to find how many square feet you need to cover.
Ms. Sue's answer is correct as far as she goes, except for one typo.
9 ft 7 inches = 9.58 feet.
After you get the total square feet, divide by 350.
I hope this helps a little more. Thanks for asking.
To calculate the total square footage of the room, you need to find the area of each wall and add them together:
1. Calculate the area of the first wall:
- Length: 11 ft
- Height: 9 ft 7 inches = 9.58 ft (rounding to two decimal places)
- Area: 11 ft * 9.58 ft = 105.38 square feet
2. Calculate the area of the second wall:
- Width: 10 1/2 ft = 10.5 ft
- Height: 9 ft 7 inches = 9.58 ft (rounded)
- Area: 10.5 ft * 9.58 ft = 100.59 square feet
3. Calculate the area of the third wall (same dimensions as the first wall):
- Area: 105.38 square feet
4. Calculate the area of the fourth wall (same dimensions as the second wall):
- Area: 100.59 square feet
5. Calculate the area of the ceiling:
- Length: 11 ft
- Width: 10 1/2 ft = 10.5 ft
- Area: 11 ft * 10.5 ft = 115.5 square feet
6. Calculate the total area to be painted by adding the areas of all the walls and the ceiling together:
- Total area: 105.38 square feet + 100.59 square feet + 105.38 square feet + 100.59 square feet + 115.5 square feet = 527.44 square feet
7. Divide the total area by the coverage per gallon of paint (350 square feet/gallon):
- Gallons needed: 527.44 square feet / 350 square feet/gallon ≈ 1.50 gallons
Rounding up to the nearest gallon, you would need approximately 2 gallons of paint to paint the room.
To find out how many gallons of paint would be required to paint a room, we need to calculate the total square footage of the walls.
First, let's calculate the area of each wall separately. The room has four walls, so we'll calculate their areas individually.
Wall 1: Length x Height = 11 ft x 9 ft 7 in
To convert inches to feet, we divide the inches by 12: 7 in / 12 = 0.583 ft
So, the height of the wall is 9 ft + 0.583 ft = 9.583 ft
Area of Wall 1 = Length x Height = 11 ft x 9.583 ft
Wall 2, 3, and 4: Width x Height = 10.5 ft x 9.583 ft
Now, let's calculate the total area of all four walls:
Total Area = (Area of Wall 1) + (Area of Wall 2) + (Area of Wall 3) + (Area of Wall 4)
Finally, we divide the total area by the coverage of one gallon of paint, which is 350 square feet, and round up the result to the nearest gallon to determine the number of gallons required.
Number of gallons required = Total Area / Coverage per Gallon
Let's calculate step by step:
Area of Wall 1 = 11 ft x 9.583 ft
Area of Wall 2, 3, and 4 = 10.5 ft x 9.583 ft
Total Area = (Area of Wall 1) + (Area of Wall 2) + (Area of Wall 3) + (Area of Wall 4)
Number of gallons required = Total Area / 350 (rounding up)
Now, let's substitute the values into the formulas and calculate.
