我有2題數學題要問,please ans with steps!盡量translate 問題至中文呀 Lisa is making a desk calendar from 2 cubes. The 2 front faces show the date, which can go from 01, 02, 03... up to 31.1 How should she number the cubes so that she can show all the dates : 01 to 31? 2 Sam wants to make a calendar that counts weeks.

He thinks that it should be possible to label two cubes so that you can make every number from 01 to 52. Explain clearly how you know that Sam is wrong.
最佳解答:
麗沙正在用兩顆正方體製作曆表 , 正方體的正面顯示日子 , 可顯示 01 , 02 , 03 , ... , 31 . 1. 她應該怎樣為正方體填上數字 , 使兩顆正方體可排列出 01 到 31 ? 2. 森想製作顥示週期的曆表 , 他認為可以在兩顆正方體上填上數字令到兩顆正方體可排列出 01 到 52 . 試詳細解釋森的想法是不可行的 . 1. 麗沙可在一顆正方體的六個面填上 0 , 1 , 2 , 3 , 4 , 5 , 另一顆填上 0 , 1 , 2 , 6 , 7 , 8 . ( 兩顆正方體都有 0 , 1 , 2 便可正確保十位數能顯示 , 而把 6 反轉放置可顥示 9 . ) 2. 假設兩顆正方體能顥示出 01 到 52 . 考慮其中四個顥示出的數是 11 , 22 , 33 , 44 , 這已經把每顆正方體的四個面佔去 , 合共剩下的四個面不可以把其他五個數字 (0,5,6,7,8) 都填上 , 這與開首的假設有矛盾 . 因此 , 森的想法是不可行的 .
