标题[机经]9月份新鲜的,几题不太确定,请大家来讨论讨论。

1.Space diangonal is a diagonal connecting two vertices on different planes.
If 边长 of the cube is 5. What is the diagonal?
请问这题要怎麽解呢?
遇到这种题型真是我的死穴
3.ABC is a triangle. D is the midpoint of BC. E is the midpoint of AC
while F is midpoint of EC, If area of triangle ABC is 24
What is the area for triangle DEF ?
关於这题我的想法是 边长变为原本的 1/2 ,且底边变为1/4
所以面积为原本的1/8 ,所以这题是 24 *1/8= 3
但是CD 上也有人说 答案是8 ,所以我想请问,这一题要怎麽思考?
4. A class of 35 students take part in an test. How many students are below
the average score?
1. The average score is 86
2. The median score is 86
这题我选E ,不过也有人 选C
所以想参考大家的意见
以上,麻烦大家。
