suppose you had four (jenga) blocks and a ledge where you want to stack these blocks such that the overhang and in doing so give a distance x extending from the ledge to the end of the last block. what configuration yields the maximum x and why is it pic related? (Hint: assume that the center of gravity is in the middle of each block)

This isnt a homework problem and I added the "hint" in myself but i cant exactly solve it myself. granted ive only seen the problem two minutes ago so I figured Id put it out there for anyone that wants to try
