Tile 15 x 30 cm. Wall 4.2 x 3 m. How many tiles do you need?
| September 27, 2021 | education
These tasks: l (the length of the tile) = 15 cm (in SI l = 0.15 cm); b (tile width) = 30 cm (in SI b = 0.3 m); L (wall length) = 4.2 m; B (wall width) = 3 m.
The required number of tiles can be calculated using the formula: N = S1 / S2 = (L * B) / (l * b).
Let’s calculate: N = (4.2 * 3) / (0.15 * 0.3) = 280 tiles.
Answer: You need 280 tiles.
