Hi All!
I felt that the Kaplan book had a wrong answer for a question. I just wanted someone to verify/comment if what I think is right. The question is:
What is the minimum number of shipping boxes Company L will need in order to ship 120 rectangular packages, all of which have exactly the same dimensions?
(1) The dimensions of the packages are 3 inches in length, 4 inches in depth, and 6 inches in height.
(2) The volume of one shipping box is one cubic foot.
"The correct answer is C (according to the book). We need both statements to solve the problem". The book assumes that the shipping boxes are cubes, and hence the dimensions are 1 foot by 1 foot by 1 foot.
My argument is, the volume of a shipping box is 1 cu. foot. This does not mean that the box needs to be a cube. Cubic foot is just the unit of measurement. The shipping box could have measured 1 foot by 1/5 foot by 5 feet. In which case, both statements are not sufficient to solve the problem.
Please let me know your comments on this. Thanks a Lot!

We're told the voume of the box is cubic ft. This is sufficient as we do not care how the dimensions work out. Whether its 1x1x1 or 1x1/5x5, the volume is always constant.
If we have a box that is 1 cubic ft, and each package has a volume, say 1/2 cubic ft, then we know each packing box is going to contain only 2 such packages.
