Subject: Direction and force in an explosion

Given a cube in which four sides have uniform strength, one side is weaker 
than the first four, but stronger than the sixth, and the remaining side is 
weaker than the other 5.  If an explosion occurs with in the cube, would it 
be possible for the 2 weaker sides to be blown off while the 4 others 
remain, or will the weakest side blow off first and all force be directed 
out that opening, leaving the other 5 sides intact?
