How to calculate the custom expansion area
In the custom furniture, metal processing, packaging design and other industries,Calculation of expanded areaIt is a key step. The expanded area directly affects the cost of materials, processing difficulty and the quality of the final product. This article will introduce in detail the calculation method of expanding area, and provide structured data and analysis based on popular topics and hot contents throughout the network for the past 10 days.
1. The basic concept of expanding area
The expanded area refers to the total area after the three-dimensional object is expanded into a two-dimensional plane. For example, customizing a metal box requires the six sides of the box to be expanded into a plane, and its total area is calculated to determine the size of the required material.
2. Calculation method of common custom products for expansion area
| Product Type | Expanded area formula | Example |
|---|---|---|
| Cuboid metal box | 2×(Length×Width+Length×High+Width×High) | 10cm long, 5cm wide, 3cm high, and 2×(10×5 + 10×3 + 5×3)=190cm² |
| Cylindrical packaging | π×diameter×height + 2×π×(diameter/2)² | Diameter 8cm, height 12cm, expansion area is π×8×12 + 2×π×4²≈401.92cm² |
| Conical parts | π×radius×(radius + oblique height) | Radius 5cm, oblique height 10cm, expansion area is π×5×(5 + 10)≈235.62cm² |
3. The relationship between popular topics and developed areas in the past 10 days of the entire network
According to search data, the following are hot topics related to "expanded area" in the past 10 days:
| Hot Topics | Relevance | Typical application scenarios |
