How many tiles required of 30sqm land if a tile is 4040cm tile?

Answer 1

If the tiles are 40x40 cm, each square meter will require 2.5 x 2.5, or 6.25 tiles. For 30 square meters then, you would need approximately 30 * 6.25 tiles, or 187.5 tiles. Of course, if you're doing real flooring and not a simple math puzzle, then .5 tiles are pretty useless, and you'd need to account not just for the area of the room, but the length and width.
