Hi Imran :)
We need information about the dimensions of both the cans and the carton. Statement 1 provides information about the dimensions of the cans, while Statement 2 simply provides the total volume. As mentioned in the explanation video, we do not have sufficient information to solve the problem, because the number of cans that fit in the carton depend on the dimensions of the latter. What we need, therefore, are the dimensions of the carton. We could be given two dimensions and the total volume or the three dimensions. Also, we are assuming that the cans are cylindrical and the carton rectangular. While this assumption are reasonable, the most complete set of information would include not only the dimensions but also the shape of the carton.
Hope this helps!
