装修材料计算简易方法（Simple calculation method of decoration materials） Simple calculation method of decoration materials Floor tile There are four kinds of common floor tiles in the market, 600mm*600mm, 500mm*500mm, 400mm*400mm and 300mm*300mm. The ground floor tiles in the precise calculation, considering the cutting loss, the loss of the purchase required plus about 3%~5%. Rough calculation method for floor tile, wall tile and stone material: The floor area of the room is 4, each floor tile area is * (1+10%) = brick number (in the formula 10% refers to the increase of the amount of wastage) Accurate calculation method of floor tile, wall tile and stone material: (room length 4 brick length) * (room width 4 brick length) = brick quantity Give an example： Rooms with long 5M and wide 4m are calculated by adopting 400mm*400mm specification floor tiles: 5m40.4m = 12.5 blocks (take 13 blocks) 4m40.4m = 10 13*10 block = brick total 130 Two wall tiles There are many kinds of wall tiles, in accounting, should first find varieties and specifications of porcelain veneer from construction drawing, then calculate the positions of tiles of the area. Then add the same area throughout the tiles of various specifications, the total area of all kinds of tiles can be the last loss plus 3%. Three, stone Ground stone The stone consumption on the ground is about the same as that of the ceramic tile, but the ground mortar is slightly thicker. In the budget amount, taking into account the cut loss, carrying loss than tile larger, should add about 1.2% of the loss. Wall stone Calculation of wall stone, in accounting should be carried out separately, according to various specifications to calculate its total area. For complex walls and modeling walls, should be calculated according to the expansion area. After the calculation of the total area of each specification, divided by the specifications, we can get the quantity of various specifications (the units are usually blocks), and finally add up to
