Note: Common GMAT Volume Trick:
When fitting 3D objects into other 3D objects, knowing the respective volume is not enough. We must know the specific dimensions (length, width, height) of each object to determine if it can fit


Right, I got it, now.

Thank you.

Yup. This is very relevant in regard to the cylinder inside a rectangular box question. It depends on the base of the box.

How do we know what are the leght and width among 3 given numbers, if need to know, of course.

12
18
20
24
30


asked an engineering friend. he said it doesnt matter what the base is in this case. we divide out the dimensions by 4. there is no need to rearrange the dimensions because the divisor is the same (all are divided by 4)

16/4 * 10/4 * 12/4
4* 2.5 * 3
we cannot have half a cube. we can only have 2 cubes. we cannot round up a cube. it is impossible.

4*2*3 = 24 max
