正方体是最常见的一种立体图形,把正方体按不同方式展开得到的平面展开图是不一样的,通过动手折纸实验探索,我们不难发现正方体的展开图不仅丰富多彩,而且呈现一定展开规律,本文分类分析如下: 一、展开图中有四个正方形的面拼接成一排,另两个正方形的面分别在这一排的两旁, The cube is the most common kind of three-dimensional figure. The plane unfolding of the cube in different ways is not the same. Through the hands-on origami experiment, we can easily find that the development of the cube is not only rich and colorful, but also presents a certain law of deployment. This article is classified and analyzed as follows: 1. In the development diagram, four square faces are spliced ​​into a row, and the other two square faces are on both sides of this row.
