How many 60cm x 60cm tiles make 18 sq meters?

To determine how many 60cm x 60cm tiles are needed for 18 square meters, first calculate the area of one tile. A 60cm x 60cm tile has an area of 0.6m x 0.6m = 0.36 square meters. Then, divide the total area (18 sq meters) by the area of one tile: 18 / 0.36 = 50. Therefore, you would need 50 tiles to cover 18 square meters.
