This problem probably falls more into the *artistic* realm, rather than the *mathematical* realm.

The problem is to pack as many "wall warts" into the smallest space possible, while having them all plugged into multiple outlet adapters (cubes, rectangles, etc).

This problem arises because every computer device needs its own wall wart -- many of which are larger than the devices they power; these devices require only a few watts, so tens can be plugged into the same circuit, but there aren't enough outlets to enable plugging in so many units.

Prior to the wall wart, the power supply was moved up the electrical cord, enabling a relatively small plug to be plugged into the outlet.

However, with the advent of wall warts, you need to be geometrically minded to figure out how to orient all the warts so that you can fit 6-8 warts into a standard (U.S.) double electrical outlet.

I should provide a picture, but something tells me my attempts wouldn't even make the junior varsity in wall wart packing.

Perhaps someone on this list is connected with Apple or Android or some other device manufacturer, and can design nicer-looking "stacking" and/or "interlocking" wall warts.

BTW, the exact same problem happens with USB hubs, since lots of things need to be plugged into USB chargers.

BTW, my nicest USB hub is in the shape of a poodle dog, with the female plugs as feet.
