Hey knight247,

Great question - and particularly in a Data Sufficiency context it's important to know that the answer is "no". So, for example, if statement 2 were not the individual dimensions but instead that "the volume of box X is 36,000 cm^3", it would not be sufficient.

Why not?

We can't assume that the blocks will fit evenly in the box. Maybe the most egregious way to demonstrate this is to imagine a box that has that volume of 36,000, but is 36,000 cm long, 1 cm high, and 1 cm deep. The volume is 36,000 cm, but you wouldn't be able to fit any blocks in it because the height and depth of the box are too small.

Or in another example, say you had a cylinder with that same volume. Because the walls of the cylinder are round but the blocks are rectangular, you have to waste some space in there - you can't get the volumes to match up perfectly.

So your calculation works if the blocks fit evenly, of if you're trying to fit liquid in a container (because it will adhere to the container's shape). But it's important to note that the GMAT can make a volume problem substantially harder just by using dimensions in which the items that fill the container won't fit the container perfectly.

Thanks Brain.
