122. 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.
答案给的是C,但是1,和2 要同时满足可能吗？（2）不是说每个相对的面得面积都为40吗？
十分感谢！

1说相邻的两个面分别是15和24
2说两个相对的面都是40
1+2 就是三个相邻面分别是 15 24 40

It's each of two. Not each of EVERY two.
