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：C
语言问题：条件2怎么理解？ 做题的时候理解的是长方体的每两个相对面的面积是40 ---> 六个面的面积都是40 ---> 体积确定 看了OG的解释，意思是说长方体其中的两个相对面每个的面积是40. ---> each of [two opposite faces of the solid] has area 40. 这样对么？？

原文说的是each of two faces .... 所以是其中两个面。如果是六个面都是他会说each of the six faces
