How many floor tiles of 30.5cm x 30.5cm to cover 4 square meters?

To determine how many 30.5cm x 30.5cm tiles are needed to cover 4 square meters, first convert the tile dimensions to meters: 30.5cm = 0.305m. The area of one tile is 0.305m x 0.305m = 0.093025 square meters. Dividing 4 square meters by the area of one tile gives approximately 43 tiles (4 / 0.093025 ≈ 43). Therefore, you would need 43 tiles to cover 4 square meters.
