Given two polygons with equal areas, one can decompose one of them into a finite number of polygons and rebuild another. This fact is known as the theorem of Bolyai-Gerwien. It is natural to ask whether this theorem is true for polyhedra with equal volumes. This question originally proposed by Bolyai and Gauss in 1844 and then by Hilbert as the Third Problem in his famous list of 23 problems, was negatively answered by Max Dehn in 1902 for polyhedra in three dimension. The main objective of this paper is to present the proof of Dehn. This article has two main parts. The first one is devoted to the concept of area: we will briefly review involving some historical facts to his formalism in geometry and prove the theorem of Bolyai-Gerwien. In the second part we will see how the concept of area and its properties can be interpreted in Euclidean space of dimension three. The main result is the theorem of Dehn-Hadwiger which is crucial to solve the problem of Hilbert for polyhedra.
