做暑假作业时遇到了一道有关正方体拼搭成几何体的题目,就查阅了资料,翻看了以前做过的一道题.题目是这样的:用小正方体拼一个立体图形,使其从左面看和从上面看分别得到下面的两个图形.问:拼这个立体图形至少需要多少小正方体?至多呢?这道题不算很难,难点在于“至多”上,至少可以从左面入手,得出立体图形有两层,第 Doing a summer vacation homework encountered a cube spell into the geometry of the subject, access to information, turned over a question previously done. The title is this: with a small square fight a three-dimensional graphics, so that from the left to see and From the above look at the following two graphics were obtained. Q: How many small cubes do you need to fight this stereoscopic graphic? At most? This question is not difficult, the difficulty is that “at most” on, at least from the left to start The three-dimensional graphics have two layers, the first
