how many tiles 10 cm by 25cm on each side are needed for a bathroom 8m by 10m?
(800/10) * (10000/25) = ____
First, let's convert the dimensions of the bathroom from meters to centimeters:
8m = 800cm
10m = 1000cm
Next, let's calculate the area of one tile:
Area of one tile = length × width
Area of one tile = 10cm × 25cm
Area of one tile = 250cm²
Now, let's calculate the total number of tiles needed:
Total number of tiles = (Area of the bathroom) / (Area of one tile)
Area of the bathroom = length × width
Area of the bathroom = 800cm × 1000cm
Area of the bathroom = 800,000cm²
Total number of tiles = 800,000cm² / 250cm²
Total number of tiles = 3200 tiles
Therefore, you would need 3200 tiles that are 10cm by 25cm each for a bathroom that is 8m by 10m.
To find out how many tiles are needed, we first need to determine the area of the bathroom and the area of each tile.
1. First, let's convert the measurements of the bathroom from meters to centimeters since the size of the tiles is given in centimeters.
The length of the bathroom is 8m, which is equal to 8 * 100 = 800cm.
The width of the bathroom is 10m, which is equal to 10 * 100 = 1000cm.
2. Next, let's calculate the area of the bathroom by multiplying the length and width:
Area of the bathroom = length * width = 800cm * 1000cm = 800,000 square centimeters.
3. Now, let's calculate the area of each tile by multiplying the dimensions of each tile:
Area of each tile = length * width = 10cm * 25cm = 250 square centimeters.
4. Finally, we can find out how many tiles are needed by dividing the total area of the bathroom by the area of each tile:
Number of tiles needed = Area of the bathroom / Area of each tile = 800,000 square centimeters / 250 square centimeters.
Calculating this, we find that 800,000 square centimeters divided by 250 square centimeters is equal to 3200.
Therefore, you will need 3200 tiles, each measuring 10cm by 25cm, to cover a bathroom with dimensions 8m by 10m.
