Math question, please help, sq meters?

If ceramic tiles are 203 mm X 203 mm, how many tiles would it take to cover an area 1 meter X 2 meters? Please show how to figure it out also.

Thanks

Answer 1

Each tile is .203 metres by .203 metres (there are 1000mm to the metre)

.203 * .203 = .041209 square metres

An area 1 metre * 2 metres is 2 square metres

Divide the number of square metres by the area of each tile

2 / .041209 = 48.533 tiles

EDIT:

You could do it another way too

Divide 1 metre by the width of a tile 1000 / 203 = 4.926 tiles

Divide 2 metres by the width of a tile 2000 / 203 = 9.852 tiles

Multiply 4.926 * 9.852 = 48.53 tiles

This way may be better if you need the calculation for an actual tile laying job.

Answer 2

Okay. So to start convert everything to either meters or millimeters. Get one unit. For this, I will convert to millimeters, I think it will be easier. So 1m x 2m, is the same as 1000mm x 2000mm. This means you need enough tiles to cover 1000mm on one side, and 2000mm on the other. To get 1000mm, from 203mm tiles, you need 5 tiles(1015mm). To cover the 2000mm, you need 10 tiles(2030mm). So you need 5 tiles by 10 tiles, which would give you a total of 50 tiles to purchase. This will cover the 1m x 2m area, with a little extra to spare on each side.

If you need an exact answer, start out the same way. 1m x 2m is the same as 1000mm x 2000mm. This means you have an area of 2,000,000 square mm. Each tile covers 203mm x 203mm, or 41,209 square mm. To see how many tiles you need, take your larger area, and divide by the area of each tile. This is 2,000,000 divided by 41,209 which gives you 48.533 tiles necessary.

Answer 3

A meter is 1000 mm devide by 203 =4.9 or 5 tiles

2 meters are 2000 mm devide by 203 =9,8 or 10 tiles

You need 5x10= 50 tiles
