The floor of a room is 3 m and 4 m long. I qm going yo tile the floor with tiles that are 20 cm wide and 50 cm long. How many tiles do I need to buy?
To find the number of tiles needed, we need to calculate the area of the floor and divide it by the area of each tile.
First, let's convert the dimensions of the floor to centimeters:
Length = 3 m = 3 * 100 cm = 300 cm
Width = 4 m = 4 * 100 cm = 400 cm
Next, let's calculate the area of the floor:
Area = Length * Width
Area = 300 cm * 400 cm
Area = 120000 cm^2
Now, let's calculate the area of each tile:
Length of tile = 50 cm
Width of tile = 20 cm
Area of tile = Length of tile * Width of tile
Area of tile = 50 cm * 20 cm
Area of tile = 1000 cm^2
Finally, let's divide the area of the floor by the area of each tile to find the number of tiles needed:
Number of tiles = Area of floor / Area of tile
Number of tiles = 120000 cm^2 / 1000 cm^2
Number of tiles = 120
Therefore, you need to buy 120 tiles.
To find out how many tiles you need to buy, you can follow these steps:
Step 1: Convert the dimensions of the floor into centimeters.
Since 1 meter is equal to 100 centimeters, the floor's dimensions are 3 m * 100 cm/m = 300 cm and 4 m * 100 cm/m = 400 cm.
Step 2: Calculate the area of the floor.
The area of the floor is equal to the length multiplied by the width. So, the area is 300 cm * 400 cm = 120,000 cm².
Step 3: Calculate the area of one tile.
The tile's area is equal to the length multiplied by the width. So, the tile's area is 20 cm * 50 cm = 1,000 cm².
Step 4: Divide the total floor area by the area of one tile to find the number of tiles required.
Number of tiles = Total area of the floor / Area of one tile
Number of tiles = 120,000 cm² / 1,000 cm² = 120 tiles
Therefore, you will need to buy 120 tiles to cover the entire floor.
To find out how many tiles you need to buy, you need to calculate the total number of tiles required to cover the area of the room.
First, convert the measurements to centimeters:
- The length of the floor is 3 m * 100 cm/m = 300 cm.
- The width of the floor is 4 m * 100 cm/m = 400 cm.
Next, find out how many tiles fit along each dimension of the floor:
- Along the length: 300 cm / 50 cm = 6 tiles.
- Along the width: 400 cm / 20 cm = 20 tiles.
To find the total number of tiles needed, multiply these two numbers:
- Total tiles needed = 6 tiles * 20 tiles = 120 tiles.
Therefore, you need to buy 120 tiles to cover the floor.
