How to calculate numbers of tiles for a given room

In this construction video tutorial, one can learn how to estimate the numbers of tiles with different dimensions for a room.

Given below different sizes of tiles to be applied :-

20 x 20 cm
30 x 30 cm
45 x 45 cm
10 x 60 cm
10 x 10 cm
225 x 45 cm
60 x 120 cm

Initially, you have to find out the total area of the room. Length and breadth are given as 300 cm and 360 cm. If you multiply them, we get = 300 cm x 360 cm = 108000 cm2.

Area of the 1st tile = 20 cm x 20 cm = 400 cm2

Numbers of tile = Area of room/Area of tile = 108000/400 = 270 numbers

This formula can be used for other sizes of tiles.

Go through the following youtube video for online demonstration.
