Difficulty: Tricky
Dennis and Richard went on a tour of a chocolate factory. At the end of the tour, they went to the reject room, where the tour guide gave Dennis a strange block of chocolate.
Richard asked Dennis to give him half. Dennis thought for a long while, and then with a knife and a cup of hot water, carefully cut the block into two identical pieces.
Can you work out where Dennis cut the block? The two pieces must be the same size and the same shape.
