At present, the height of building floors is generally about 3 meters. According to 3 meters, how many meters is the 50-story building? The 50-story building should be150m.

High-rise buildings, that is, high-rise buildings, are traditionally more than 9 stories, and buildings with elevators can be called high-rise buildings. However, in modern society, due to the increasing number and height of high-rise buildings, a new definition of high-rise buildings has been added. Generally, the floor above 18 is called high-rise building, and the floor above 100 meter can be called super high-rise building or skyscraper.

We should consider the air quality when choosing floors, and think that good air will affect the physical and mental health of individuals and families. The interval of urban dust is generally about 20-35 meters, and it is above the dust layer when it is higher than 35 meters. So if you avoid the dust layer in the city, buy a house with a floor above 12. In addition, from the point of view of dust, noise and sight, the higher the floor, the better.
