How many 31cmx31cm tiles will it take to cover 14 sq meters?

To determine how many 31cm x 31cm tiles are needed to cover 14 square meters, first convert the tile dimensions to meters: 31 cm is 0.31 m, so the area of one tile is 0.31 m x 0.31 m = 0.0961 square meters. Next, divide the total area to be covered (14 square meters) by the area of one tile (0.0961 square meters): 14 / 0.0961 ≈ 145.4. Since you can't use a fraction of a tile, you'll need 146 tiles to cover 14 square meters.
