Mr Xu is prepared to come here He specially brings two drawings, namely the elevation of his own shoe cabinet and bookcase, which are annotated with the data of length, width and height Even the area of the wall and ceiling of his own house has been estimated in advance by Mr Xu The total area is 260 square meters Now, I will sort out the ideas and list the problems that Mr Xu needs to solve 1 The total area of ceiling and wall is 260 square meters How much emulsion paint is needed? 2 The length, width and height of self-made two door shoe cabinets with louver shape are 0.9 m, 0.3 m and 1 m respectively How much paint is needed? 3 The self-made bookcase is 4.4 m long and 2.4 m high, with a row of glass doors in the middle How much paint does the bookcase need to be painted? In order to give Mr Xu a more accurate answer, the reporter specially consulted the decoration company expert Li Yongsheng, and gave a detailed analysis and answer to the questions raised by Mr Xu According to Lin Yongsheng, the amount of emulsion paint used for ceiling and wall is about 10 square meters according to one brush In short, one tenth of a kilogram of emulsion paint needs to be used per square meter of wall surface The total area of the ceiling and wall of Mr Xu's house is 260 square meters It takes about 260 * 1 / 10 = 26 kg according to one brush Generally speaking, the ceiling and wall need to be painted twice, so the amount of emulsion paint required for Mr Xu to brush the ceiling and wall is about 26 * 2 = 52 kg There are two methods to calculate the paint consumption of the self-made shoe cabinet: one is to calculate the paint consumption of the self-made shoe cabinet according to the number of panels used in the shoe cabinet according to one brush, and one kilogram of paint can brush about 15 square meters of panels, that is to say, each square meter of panel needs to use 1 / 15 kilogram of paint How many panels are used for the parts of the shoe cabinet that need to be painted? Let's assume that X panels are used, and the area of one panel is about 3 square meters According to the calculation of brushing, the paint consumption of the shoe cabinet is about 1/15*3*X kg According to the calculation of "three bottoms and two sides", the amount of primer and finishing coat shall be multiplied by three times and two times respectively, i.e 1 / 15 * 3 * x * 3kg and 1 / 15 * 3 * x * 2kg Method 2: according to the calculation of the panel area to be painted, take this self-made shoe cabinet as an example Except for the back and bottom, the top, front and both sides need to be painted The length, width and height of this shoe cabinet are 0.9m, 0.3m and 1m respectively Then, the area of the top, front and two sides are 0.9 * 0.3m2, 0.9 * 1m2, 0.3 * 1 * 2M2, namely 0.27m2, 0.9m2 and 0.6m2 Because the two doors of the shoe cabinet are in the shape of shutters, the paint consumption is relatively more The paint consumption of these two doors must be multiplied by a factor of 1.2, that is to say, brushing these two doors is equal to brushing 0.9 * 1.2 square meters of panels Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
