As everyone knows, some 'guerrillas' masters love to be greedy and cheap, like to touch and get some points. If you can't eat the amount of paint and latex paint, you will inevitably suffer. Mr. Xu purchased a new 120 square meter home in Shitong District. After a few months of "Jian Teng", the woodwork is about to be painted, and Mr. Xu has encountered a difficult problem.
"Trouble me for a moment, how much paint should be used in my shoe cabinets and bookcases, how much latex paint is needed on the wall." Mr. Xu is well prepared. He specially brought two drawings, one for his own shoe cabinet and the bookcase. The elevation map is marked with data such as length, width and height. Even the size of the wall and ceiling of the house, Mr. Xu also estimated in advance, a total of 260 square meters.
Now, Xiaobian sorts out the ideas and lists the questions that Mr. Xu needs to solve.
1. The total area of ​​the ceiling and wall is 260 square meters. How much latex paint is needed?
2, the two-door shoe cabinet with self-made louver shape, length, width and height are 0.9 meters, 0.3 meters, 1 meter respectively. How much paint is needed?
3. The self-made bookcase is 4.4 meters long and 2.4 meters high, with a row of glass doors in the middle. How much paint does this bookcase need to brush?
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 question raised by Mr. Xu.
Ceiling and wall latex paint usage
Lin Yongsheng said that according to the brush calculation, 1 kg of latex paint can cover about 10 square meters of wall surface. In other words, 1/10 kg of latex paint is needed per square meter of wall.
Mr. Xu’s total ceiling and wall area is 260 square meters. According to the brush, it takes about 260*1/10=26 kg. Generally speaking, the ceiling and the wall need to be painted twice, then the amount of latex paint required by Mr. Xu to brush the ceiling and the wall is about 26*2=52 kg.
Paint usage of homemade shoe cabinets
There are two ways to calculate the amount of paint used in a homemade shoe cabinet:
Method 1: Calculate the number of panels used in the shoe cabinet
According to the brush calculation, 1 kg of paint can cover about 15 square meters of the panel, which means that 1/15 kg of paint is needed per square meter of panel. So how many panels do you need to paint on this shoe cabinet? Let's assume that X panels are used. The area of ​​a panel is about 3 square meters. Then, according to the brush, the paint consumption of this shoe is about 1/15. *3*X kg. According to the calculation of “three bottoms and two sidesâ€, the amount of primer and topcoat is multiplied by 3 (pass) and 2 (pass) respectively, ie 1/15*3*X*3 kg and 1/15*3*X*2 kg.
Method 2: Calculate the area of ​​the panel to be painted as needed
In addition to the back and bottom, the top, the front and both sides need to be painted. The length, width and height of this shoe cabinet are 0.9 meters, 0.3 meters and 1 meter respectively. Then, the areas of the top surface, the front surface and the two side surfaces are 0.9*0.3 square meters, 0.9*1 square meters, 0.3*1*2 square meters, that is, 0.27 square meters, 0.9 square meters, and 0.6 square meters, respectively. Because the two doors of the shoe cabinet are louvered, the amount of paint used is relatively more. The paint amount of the two doors is multiplied by a factor of 1.2, that is, the two doors of the shoe are equal to the panel of 0.9*1.2 square meters. .
