an ant ,it will climb along the arris .it will start from point A,but each arris can not be repeated,then the ant must come back to point A,but each arris can not be repeated ,then the ant must come back to point A.Question:how far does it climb at most?注:图片发不上来,是一个横着的长方形,上下两个面应该是正方形,A好像是高、、、如果不是就是就是一条长、、六年级奥数,我英语不好,
一道英语奥数题:there is a box,its length is 6cm,the width is 5cm ,a
一个盒子,长6宽5高4cm,有只蚂蚁,沿着棱从A爬,路线不能重复,但是必须回到a,问这条虫最多爬多远?
估计答案是6*4+5*2+4*2=42cm
你可以自己再试试看,看看有没有更长.
再问: 棱长之和也算吗?
再答: 问的就是棱长之和,这个问题直观点就是说,假设真有一个盒子,拆开来,拆成平的,在不重复边的情况下,边长最大的四方形,长度是多少?
