To calculate the number of square yards of wallpaper needed to paper the four walls of the room, we first need to find the total surface area of the walls. The total surface area can be calculated by finding the sum of the areas of each wall.
Step 1: Find the area of each wall:
- Wall 1: Length * Height = 24 feet * 9 feet = 216 square feet
- Wall 2: Length * Height = 24 feet * 9 feet = 216 square feet
- Wall 3: Width * Height = 18 feet * 9 feet = 162 square feet
- Wall 4: Width * Height = 18 feet * 9 feet = 162 square feet
Step 2: Add up the areas of all four walls:
216 square feet + 216 square feet + 162 square feet + 162 square feet = 756 square feet
Now, in order to convert square feet to square yards, we need to divide the total square footage by the conversion factor of 9. Since there are 9 square feet in 1 square yard, we divide the total square footage by 9.
Step 3: Convert square feet to square yards:
756 square feet / 9 = 84 square yards
Therefore, 84 square yards of wallpaper are needed to paper the four walls of the room.
Let's first convert feet to yards.
The room is 8 yards long, 6 yards wide, and 3 yards high.
Two walls are 8 yards by 3 yards = 24 square yards each.
The other two walls are 6 yards by 3 yards = 18 yards each.
I think you can take it from there. We'll be glad to check your answer.
