(1) Find the maximum number of cubes of equal size such that you can place each one to touch the rest.
(2) Same as 1. But you can choose any size of a cube.
BTW, if you have time to kill, you can try any regular shape, such as 长方体,半球, etc.
我觉得,不管是对于问题(1)还是(2),答案都是8。即,在3维的直角 座标系的每个象限各放一个立方体,所有8个立方体在原点相互接触。 我想象不出更大的数目了。 |
