A room is 8 m × 5 m. Tiles are 0.5 m × 0.5 m. How many tiles are needed?
Question: A room is 8 m × 5 m. Tiles are 0.5 m × 0.5 m. How many tiles are needed?
Solution:
Use area and round up because you can't buy a fraction of a tile.
Number of tiles = ⌈ Room area / Tile area ⌉
Room area = 8 × 5 = 40 m²
Tile area = 0.5 × 0.5 = 0.25 m²
Tiles = ⌈ 40 / 0.25 ⌉ = ⌈ 160 ⌉ = 160
So, you need 160 tiles.
Number of tiles = ⌈ Room area / Tile area ⌉
Room area = 8 × 5 = 40 m²
Tile area = 0.5 × 0.5 = 0.25 m²
Tiles = ⌈ 40 / 0.25 ⌉ = ⌈ 160 ⌉ = 160
So, you need 160 tiles.
Equation/Formula:
tiles = ⌈ (roomLen × roomWid) / (tileLen × tileWid) ⌉
