But still I am confused at the explanation given by Kaplan.
As per Kaplan:
1) Sufficient.

2) if x,y,z is length, breadth and Height. Then xy=120, yz=100 and xz=100 (As surface of [b]EACH of the facing side is given[\b] . Hence it is not sufficient to get the volume.(This is what Kaplan says)

But what I feel is if xy=120, yz=100, xz=100. Then (xyz)^2 = 120*100*100
As volume cannot be negative hence, (2) is also sufficient to find the volume.

To my understanding (D) should be the answer but as per Kaplan (A) is the answer. (Sometime books can also be wrong!)

I wasnt sure initially what they ment my cubiod. Now, if in fact, that means a cube where two of the three sides must equal, then the answer MUST BE D.

In a cube xy=120 =>> x=y =>> x^2=120 ===> x or y =Sqrt(120)=~11

from the second statement we have x which is sqr(120)*z=100, ==>
z~=9.1 There is only one possible value for Z

Conclusion we know that x=y, therefore Volume is 120*9.1=1092

The are no two possible answers, therefore statement (2) is enough.
