I think you need the hide surfaces script.

From the side view select the top faces and map them.
Then hide those top faces.
Next from the top view select the leftside faces and map them.
Then hide the leftside faces.
Finally select and map the right side faces.
Be careful where each mesh is mapped onto the texture, so they don't overlap.
There's probably a better method, but that's all I can think of.
