Distinguish between indoor walls and outdoor walls.
The purpose and structure of indoor wall and outdoor wall are different, so it is necessary to calculate them separately in order to master the area of each wall more accurately.
Understand the structure and types of walls.
Different wall types and thicknesses will affect the calculation method of area. For example, hard wall, light wall and ceiling area wall all have their own calculation methods, which should be selected according to the actual situation.
The calculation methods of straight wall and inclined wall are different.
The area of a straight wall is the length multiplied by the height, while the inclined wall needs to use Pythagorean theorem to calculate the length multiplied by the height. When calculating the height of inclined wall, the influence of inclined angle should also be considered.
Influence of opening parts such as doors and windows.
Opening parts such as doors and windows need to be calculated separately and deducted from the total area. When calculating the outdoor wall area, we should also pay attention to the location of doors and windows, because these places need ventilation and lighting. So we need to subtract the area of these spaces to ensure the accuracy of the calculation.
abstract
To accurately calculate the wall area, it is necessary to have a complete structural diagram, understand the calculation methods of different wall types, and fully consider the influence of doors and windows and other openings. When decorating a new house, accurately calculating the wall area is one of the important steps to ensure the decoration effect.
