How would you manage to figure out how to put the square shape together?

Possibly the oldest known mathematical puzzle, developed by the famous Greek mathematician Archimedes around 2200 years ago. The puzzle consists of 14 pieces of different shapes and the objective is to combine the piece to form a square. Mathematician Bill Cutler determined in 2003, using a computer, that there are 536 unique ways to fit the square shape.
