正方体的展开图有很多种,而且我们知道正方体的展开图实际上就是六个相同的正方形的组合.下面我们来研究正方体有多少种不同的展开图.为了使找出的各种情形既不重复,也不遗漏(两个图形通过旋转、平移或翻折能够重合,只能视为一种),不妨按照正方形个数最多的一排进行分类,结合推理、想象,看看正方体的展开图到底有多少种. There are many kinds of cube expansion, and we know that the cube expansion is actually a combination of six identical squares. Now let's study how many different expansion of the cube. In order to find out the various situations are not repeated , Also do not miss (two figures by rotating, panning or folding can overlap, can only be regarded as one), may wish to follow the largest number of squares in a row for classification, combined with reasoning, imagine, look at the cube of the expansion in the end How many kinds?
