1F：推 tingting88:第一题可以解释成 3,3,4 跟 3.5,3.5,4 140.112.4.249 05/27 21:01
2F：推 tingting88:第三题1面的面积=150/6=25 所以边长=5 140.112.4.249 05/27 21:06
3F：→ tingting88:第四题并没有注明他用了多少油 140.112.4.249 05/27 21:08
4F：推 tingting88:第二题很怪 6又15/16=111/16=3*37/16 140.112.4.249 05/27 21:17
5F：→ tingting88:可是题目里面并没有出现跟37有关的 140.112.4.249 05/27 21:17
6F：推 DynastyEG:怀疑第二题题目是to the 111th mark 59.120.8.222 05/28 01:15
