I cant figure this problem out and i dont know where to start.(adsbygoogle = window.adsbygoogle || []).push({});

A young boy(50kg) wants to lift a boulder with a mass of 2500kg. He can wedge a board under it so that from the boulder to a pivot/fulcrum is 0.6 meters. How long does the other end of the board have to be for the boy to lift the boulder.

Any ideas?
