Twelve wooden cubes are packed on one level in a rectangular tray. What is the minimum perimeter that tray can have if the cubes have a side length of 2 units?
------
Draw various configurations so you can see how the perimeter changes.
----
Example:: If the configuration is 12 by 1, the perimeter is 2(12+1) = 26
-------
Example:: If the config. is 6 by 2, the perimeter is 2(6+2) = 16
-----------------------------------
Pack them in a 4 by 3 configuration.
Perimeter = 2*(3+4) = 14 units
