walkway
3 ft = 36 in
11ft = 132 in
4in * 6in. = 24 square inch
36in * 132in = 4752 square inch
4752/24 = 198 bricks
A walkway, huh? That's a brick-tastic idea! To calculate how many bricks you'll need, you'll first need to find the area of the walkway. So let's convert the measurements to inches first.
The walkway measures 36 inches by 132 inches (since 3ft = 36in and 11ft = 132in).
Now you just have to find the area of the walkway by multiplying the length and width, which gives us 4,752 square inches.
Now, let's find the area of one brick, which is 4 inches by 6 inches, giving us 24 square inches.
To find out how many bricks you'll need, you can simply divide the area of the walkway by the area of one brick. That gives us 198 bricks.
So, you'll need a whopping 198 bricks to complete the walkway! May the brick-laying force be with you!
To calculate the number of bricks needed, we need to find the total area of the walkway and divide it by the area of one brick.
1. Convert the measurements of the wall and brick to the same unit:
- The width of the wall is 3 ft, which is equal to 36 inches (1 ft = 12 inches).
- The length of the wall is 11 ft, which is equal to 132 inches.
2. Calculate the area of the walkway:
- The area of the walkway is the product of the width and length of the wall.
- The area of the walkway = 36 inches * 132 inches = 4752 square inches.
3. Convert the measurements of the brick to square inches:
- The width of the brick is 4 inches.
- The length of the brick is 6 inches.
4. Calculate the area of one brick:
- The area of one brick is the product of the width and length of the brick.
- The area of one brick = 4 inches * 6 inches = 24 square inches.
5. Determine the number of bricks needed:
- Divide the area of the walkway by the area of one brick to find the number of bricks needed.
- Number of bricks = Area of walkway / Area of one brick = 4752 square inches / 24 square inches = 198 bricks.
Therefore, it will take 198 bricks to complete the walkway.
To determine how many bricks will be needed to complete the walkway, we first need to calculate the total area of the walkway and then divide it by the area of each brick.
1. Calculate the area of the walkway:
- The dimensions of the walkway are 3 ft by 11 ft.
- Convert the dimensions to inches since the area of the bricks is given in inches.
- 1 ft = 12 inches, so the dimensions become 36 inches by 132 inches.
- Calculate the area of the walkway: 36 inches * 132 inches = 4752 square inches.
2. Calculate the area of the brick:
- The dimensions of the brick are 4 inches by 6 inches.
- Calculate the area of the brick: 4 inches * 6 inches = 24 square inches.
3. Determine the number of bricks needed:
- Divide the total area of the walkway by the area of each brick: 4752 square inches / 24 square inches = 198 bricks.
Therefore, it will take 198 bricks to complete the walkway.
