Dear firends:
I have a problem with GMAC answer to the question number 130 of Quantitative review second edition. I know that "statement 1" is not sufficient but why "statement 2" is not sufficient ?

the question is as follows:

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.

it is said that each of two opposite faces has area of 40 it means the solid is a cube (cube is also a rectangular solid) and length of each edge is 40^(1/2).

IMO if it was said thata pair of two opposite faces of the solid has area of 40 then GMAC answer was correct.
