Well, assuming the room is cuboid in shape, the answer is option D. My reasoning is as follows:
If you have less than or equal to 36 small parcels, you're good. If you've got more, they won't fit.

He packed 18 parcels of 2 cubic metres so now he know both height and floor area of the store now all that matters is how many small parcels are there so he can calculate whether they will fit or not
C, the highlighted option is the correct answer btw!
Now basically we have the info as follows :-
base area 9 sq. Mts
hence total volume of container is 36 cubic mts
Now we have cubes of volume 1 cubic metre ....
we know that no. Of small parcels =
volumr of container ÷ vol. Of small parcel (the cube)
hence in order to have all the parcels to be exactly fit in the container we must know the number of parcels
