数学求指教
What is the volume of a certain rectangular solid?
(1) Two adjacent faces of the solid have areas 15 and 24, respectively.
(2) Each of two opposite faces of the solid has area 40.
answer is C
(2)中是不是说任意两个相对的面的面积都是40?这样的话不就是说每个面都是40了,跟15和24矛盾了啊
这个each of two opposite faces 怎么理解呢?觉得题目意思不明确,求指教啊 |
