I couldn't figure this one out. Any help is GREATLY appreciated.
what is the Max number of rectangular boxes, each measuring 2 inches by 3 inches by 5 inches, that can be packed into a rectangular packing box measuring 18 inches by 19 inches by 35 inches, if all boxes are aligned in the same direction?
A. 352
B. 378
C. 399
D. 432
E. 447
I THINK the fact that the boxes are aligned in the same direction has something to do with the answer.

We have to find out the way in which side of the bigger rectangle can be a multiple of the side of the smaller rectangle.(Try it to maximum)
In that way the 5 inch side should be aligned to the 35 inch side ( 7 layer)
3 inch side should be aligned to the 18 inch side. (6 layer)
and 2 inch side should be aligned to the 19 inch side.(9 layer)(Note(optional)): we can align 2 inch side to 18 inch side)
Maximum number of rectangles =7*6*9=378 Answer is B,
Consider KUDOS if it helped u in some way.
