To be precise, in theory*, you’ll need 300 tiles of 20 x 20 cm.
How? Well each metre would require five 20 x 20 cm tiles laid side-by-side.
So for the length of 4m, you would need 20 (4 x 5) tiles across and for the breadth of 3 m, you would need 15 (3 x 5) tiles across.
So in total you would need 20 x 15 = 300 tiles to cover the floor.
* remember I mentioned “in theory” above? Why?
Because in practice you would need a few more tiles. Why?
As a backup: Tiles can break when laying or cutting (if needed) and hence cannot be used as they would be aesthetically unpleasing. Hence to cover this wastage yo
A tile measures 20 cm by 15 cm. How many tiles are required to cover a wall of 5 m by 3 m?
How many square tiles of side 10 cm each will be needed to tile a floor that is 300 cm long and 500 cm wide?
The length and breadth of a tile are 10 cm and 12 cm. How many tiles will be required to cover a floor of a room whose length and breadth are 4 m and 3 m?
How many square tiles of a side does 40 cm need to build a room of length 16 m and breadth 10 m?
A floor 10 m long and 8 m broad is to be paved with square tiles of side 0.5 m. How many tiles will be needed?
Length of floor = 4 metres
breadth of the floor = 3 metres
Area of the floor = 4m * 3m = 12 sq.m
lenght of the tile = 20cm
area of the tile = 20 * 20 = 400cm^2
12 sq. m = 120000 sq. cm
no.of tiles required = 120000/400 = 300 tiles
therefore, you require 300 tiles to cover your floor
