A rectangular solid S, has dimensions 4 by 9 by k. What is the value of k?

(1) 4 < k < 9
k could take any value in the range(5,6,7,8)
Hence, we cannot arrive at a unique value of k (Insufficient)

(2) A cube of side 6 has the same volume as rectangular S.
If the cube has the same volume as the rectangular solid, which is a cuboid
$$4*9*k = 6^3$$ -> $$k = 6$$ (Sufficient - Option B)
