# How to find out the number of tiles required for a floor

In this construction video tutorial, you will learn how to compute quantity of tiles required in building rooms or bathrooms.

Initially, you have to determine the area of the room where the tiles will be placed.

Suppose, there is an L-shaped room and it is divided as part A and part B.

Length of room A = 3 meter

Breadth of room A = 2 meter

Length of room B = 6 meter

Breadth of room B = 2 meter

At first, calculate the area of A as follow :-

Area = Length x Breadth

After putting the above values of room A, we get

Area = 3 x 2 = 6 square meter

Then, calculate the area of B as follow :-

Area = Length x Breadth

After putting the above values of room A, we get

Area = 6 x 2 = 12 square meter

Therefore, total area = area of A + area of B = 6 + 12 = 18 square meter

Suppose the length of one tile = 600 mm = 0.6 m and breadth = 600 mm = 0.6 m

So, area of one tile = length x breadth = 0.6 x 0.6 = 0.36 square meter

There, no. of required tiles = Total Area / Area Of One Tile = 18 / 0.36 = 50 Nos. (approx)

But, you have to also consider the wastage that may occur in construction site.

The wastage differs from site to site as well as according to room sizes.

Assume, standard wastage is 5%.

So, 50 + 5% of 50 = 50 + (5/100 x 50) = 50 + 2.5 = 52.5 numbers = 53 numbers

To get more clear idea, go through the following video tutorial.
