Statement 1 :
Not Sufficient -> As we don't know the dimension of the container. (It is not liquid, which you can just pour into the box. You need to fit it the box. So the length and breadth matters. Based on that it may fully fit or it may leave some spaces.)

Statement 2 :
Not sufficient -> Now we know the dimension (length & breadth) BUT not the volume, which again is needed as with the same length and breadth but different height you can put different numbers of cube.

Combing 1 and 2 : Sufficient , As we have all the dimensions (length, breadth and height) of the cube. We can determine the no. in this case.

Hence C

Thanks
