Decoration need to use a lot of decoration materials, each kind of material and how much to buy? Xiao Bian this has five formulations of the amount of decoration materials, look at the decoration of the decoration of the purchase of the material. Decoration owners to apply the formula to calculate the number of home decoration decoration materials should be used!

The calculation formula of five materials used in decoration

First, the amount of floor tile

One hundred square meters of the amount of =100/[(block length + gray seam width) * (block width + gray seam width)] x (1+ loss rate)

As a concrete example of application, the living room decoration with 50cm * 50cm tiles, seam width 2mm, tile loss rate equal to about 1%, then the renovation of 100 square meters need to use the number of pieces of tile algorithms as follows: 100/[(0.5+0.002) * (0.5+0.002) * (1+0.01) = 401. Of course, the general living room area is less than 100 square meters, then use 401/100 to calculate the amount of one square meter, about 4, and then measured the number of square meters living room.

Floor tile = floor tile number * floor tile price

Second, the amount of the door

The amount of material outside the box door = length x door frame width

For example: composite wood material door, door frame length 2.7M, width of 1.5M, the amount of materials are as follows:

The package material dosage of =2.7 * 1.5=4.05 square meters

Third, wallpaper dosage

Wallpaper amount = (high shield length) x (wide shield width) * wall number - gate area - window area

Shielding length refers to the length or width of the combination of public areas or coincidence part.

Small series of examples to explain to you: Putie wall width 5m, height 2.5m, shielding length is 24cm, the calculation of the area of doors and windows were obtained 2.8 square meters and 3.6 square meters, so the wall requires paving wallpaper for [amount (2.5 - 0.24) * (5 - 0.24 2.83.6)] * 4 - about 36.6 square meters.

With this method the need of each wall wallpaper amount, then the calculated result is the sum of the total amount of wallpaper decoration needs to be used, and then multiplied by the price is calculated the wallpaper, wallpaper decoration materials total cost.

Fourth, floor dosage

The floor is divided into two vertical and horizontal length to calculate the amount of:

Vertical floor use = room length / floor length

Floor width = room width / floor width

And then calculate the amount of vertical * horizontal consumption, is the total amount of floor decoration materials. One thing to note is that the calculation of the amount of material to be used in the calculation of the floor, not four homes into the five. Vertical calculation is less than half a piece of computing block, more than half a piece of block.

Floor price = total amount * unit price

Floor loss = floor area - housing area

Floor loss rate = floor loss / housing area

Note: General Floor loss rate is not greater than 5%
