Tiles are 150x150 how many tiles in square meter?

To determine how many 150x150 mm tiles fit in a square meter, first convert the tile dimensions to meters: 150 mm = 0.15 m. The area of one tile is 0.15 m x 0.15 m = 0.0225 m². Since one square meter is 1 m², you divide 1 m² by the area of one tile: 1 m² ÷ 0.0225 m² = approximately 44.44. Therefore, you can fit 44 tiles in a square meter, with some leftover space.
