The height of one cylindar is 5. The volume of a box is 12. Ask how many boxes of this size can be put into the cylindar?
1. one edge of the box is 2
2. the diameter of the cylindar is 3

I think the answer is C.  No box can be put into. Is that correct?

Thanks!!!!!

I vote for one box

一个盒子不行吧, 2*a*b=12

a=1,b=6

or

a=2,b=3

而圆锥要至少 1.5 by 1.5 by 5 的盒子才行, 但是上边的都不满足

讨论一下

我觉的是E

一边是2的话，另外两边ab=6

圆柱体的尺寸是1.5*1.5*5

a，b未必都是整数啊

1*2*6就放不进去

但是2*1.2*5也许能放的进去

这样应该是E吧

大家讨论

楼上说得没错，我现在也支持E了！
