how many tiles 10cm by 25cm on each side is needed for a bathroom 8m by 10m? I need help on how to solve it... I learned how to do this in 8th grade but I'm now in 10th and I forgot how to do it. I'm preparing for the highschool exit exam and I need to do this problem but the teacher expects me to know it already so she won't go over it. So please someone help me.

8 m = 800 cm

10 m = 1000 cm

800 / 10 = 80
1,000 / 25 = 40

80 * 40 = ________ tiles

3200! BLESS YOUR SOUL KIND PERSON THANK YOU SO MUCH!!

Ah, the joys of high school exams! Let's clown around with this math problem, shall we?

To find out how many tiles you need for the bathroom, we can break it down step by step. First, let's convert the measurements to the same unit. You mentioned that the tiles are 10 cm by 25 cm, so let's convert the bathroom dimensions as well:

8 meters is equivalent to 800 centimeters (8 x 100), and 10 meters is equivalent to 1000 centimeters (10 x 100). Now we have a bathroom that's 800 cm by 1000 cm.

Next, we divide the bathroom's length by the length of the tile. So, 800 cm ÷ 10 cm = 80 tiles per row.

Then, we do the same thing with the width: 1000 cm ÷ 25 cm = 40 tiles per column.

Now it's time to find the total number of tiles. To do that, we multiply the number of tiles per row by the number of tiles per column:

80 tiles/row x 40 tiles/column = 3200 tiles in total.

Voila! You would need approximately 3200 tiles for your bathroom.

Now, remember that this calculation assumes the tiles perfectly fit without any waste or need for cuts. So, if you want to account for trimmings and extra tiles, you might want to grab a few extra, just in case. Good luck with your preparations for the high school exit exam, you've got this!

To find out how many tiles are needed for a bathroom with dimensions 8m by 10m using tiles with dimensions 10cm by 25cm, you can follow these steps:

Step 1: Convert the dimensions of the bathroom to the same unit as the tiles. Since the dimensions of the bathroom are given in meters, we need to convert them to centimeters because the tile dimensions are in centimeters.
- Length of the bathroom: 8m = 800cm (1m = 100cm)
- Width of the bathroom: 10m = 1000cm

Step 2: Calculate the area of the bathroom.
- Area of the bathroom: Length × Width = 800cm × 1000cm = 800,000cm²

Step 3: Calculate the area of a single tile.
- Area of a tile: Length × Width = 10cm × 25cm = 250cm²

Step 4: Divide the area of the bathroom by the area of a single tile to find the number of tiles needed.
- Number of tiles needed: Area of the bathroom ÷ Area of a tile = 800,000cm² ÷ 250cm² = 3200

Therefore, you would need 3200 tiles to cover the bathroom with dimensions 8m by 10m using tiles with dimensions 10cm by 25cm.

To find out how many tiles are needed for a bathroom of dimensions 8m by 10m using tiles of dimensions 10cm by 25cm, you can follow these steps:

1. First, convert the dimensions of the bathroom to centimeters. Since 1 meter is equal to 100 centimeters, the bathroom dimensions become 800cm by 1000cm.

2. Determine the area of a single tile. Multiply the length and width of the tile to find its area. In this case, the area of a tile is 10cm x 25cm = 250 square centimeters.

3. Calculate the total area of the bathroom. Multiply the length and width of the bathroom to find its area. In this case, the area of the bathroom is 800cm x 1000cm = 800,000 square centimeters.

4. Divide the total area of the bathroom by the area of a single tile to find the number of tiles needed. In this case, 800,000 square centimeters (bathroom area) ÷ 250 square centimeters (tile area) = 3,200 tiles.

Therefore, you would need 3,200 tiles of dimensions 10cm by 25cm to cover a bathroom of dimensions 8m by 10m.

It's normal to forget things over time, so don't worry about it! I'm here to help you refresh your memory. Good luck on your high school exit exam!
