how come?

how come on task boxes i keep getting wrong answer I mean the way is that:

Volumes of the objects shouldnt be same
and ratio of the volume1 and volume2 are same as the ratio of the d1 with d2 or s2 or v2.... for all of them.
Right ? or am i missing something here?
thanks

Don't try solving it using volume, just look the sides of the boxes. Compare them.

well, shapes are also important. for example a box 1x5x1 has smaller volume than a box 2x2x2, but it can not fit into it.
