主材计算方法（The calculation method of material） The calculation method of material: Paint latex paint Coating latex paint packaging is basically divided into 5 liters and 15 liters of two specifications. To the common family in 5 liter capacity as an example, 5 liter brushing area for two times 35 square meters. Rough calculation: ground area *2.5/35= using buckets Accurate calculation method: (length + width) *2* room height = wall area Length * width = area of top surface (wall area + top surface area - door and window area) /35= bucket usage. With long 5m, width 3M, high 2.9m room, for example, indoor walls, the top brushing area is calculated as follows: The wall area: *2*2.9m=46.4 square meters (5m+3m) Top surface area: =15 square meters (5m*3m) The amount of paint: (46.4+15) /35 square meters =1.7 barrels Composite floor Rough calculation method: The ground area (1.2m*0.19) / *105% (5% loss) = number of floor A precise method of calculation: (the length of the room / plate length (width) * plate width = floor / room number) Take long 5m, wide 4m room, choose 900*90*0.18m specification floor as an example: Room 5m/1.2m=5 block, room width 4m/0.19m=22 block Length 5 pieces * width 22 block = total 110 pieces of board Tips: Composite wood flooring in the pavement will be 3%-5% of the loss, if the area calculation, do not ignore this part of the amount. Solid wood flooring Common specifications are 900*90*18mm 750*90*18mm, 600*90*18mm Rough calculation method: Room area / floor area of *1.08 (8% for loss) = use floor blocks A precise method of calculation: (room / floor length) * (room width / floor width) = floor blocks For long 8CM, wide 5M rooms, with 900*90*0.18m standard floor, for example, room length 8m/, board length 0.9m=9 block. Room width 5m/, board width 0.09m=56 block. Length 9 pieces * width 56 block = total 504 pieces of board Tips: Solid wood flooring, usually in the 5%-8% of the loss, in calculation to take into account. Floor tile： The specifications
