Length, width and height are usually used to describe the size of three-dimensional objects. In three-dimensional space, we usually use square units to represent the area and cubic units to represent the volume. So the length, width and height are used to calculate the volume of an object, not the square. If you want to calculate the volume of an object, you need to express the length, width and height of the object with numerical values, and keep the consistency of units, usually in meters, centimeters or millimeters. The calculation formula is as follows: volume (V)= length (L) × width (W) × height (H).
If you want to calculate the area (square is the area unit), you only need to multiply the lengths of two sides, such as length * width, length * height, width * height. For example, if the length, width and height of a problem are 1m, 2m and 3m respectively, then the object has three pairs of faces with the same size, and its squares are 1m * 2m = 2m, 1m * 3m = 3m and 2m * 3m = 6m respectively.
Regional usage scenario
1. Geography and real estate: In the field of geography and real estate, area is used to measure the size of geographical areas such as land, villages, cities, lakes and rivers. The real estate industry uses area to represent the size of different properties and help buyers choose the right housing area.
2. Architecture and architectural design: In the field of architecture, area is used to calculate the total plane area of a building, including rooms, floors and the whole building. Architects use area to plan room layout and architectural design.
3. Agriculture: In the field of agriculture, area is used to measure the size of land and the area of farmland, helping farmers plan planting and predict the harvest of crops.
4. School and education: In school education, area is used for teaching and learning, such as calculating the area of classrooms, campuses and libraries.
