Web26 rows · Hilbert's problems are 23 problems in mathematics published by German … The third of Hilbert's list of mathematical problems, presented in 1900, was the first to be solved. The problem is related to the following question: given any two polyhedra of equal volume, is it always possible to cut the first into finitely many polyhedral pieces which can be reassembled to yield the second? … See more The formula for the volume of a pyramid, $${\displaystyle {\frac {{\text{base area}}\times {\text{height}}}{3}},}$$ had been known to Euclid, but all proofs of it involve some form of limiting process or calculus, … See more Dehn's proof is an instance in which abstract algebra is used to prove an impossibility result in geometry. Other examples are See more Hilbert's original question was more complicated: given any two tetrahedra T1 and T2 with equal base area and equal height (and therefore equal volume), is it always possible to find a finite number of tetrahedra, so that when these tetrahedra are glued in some … See more • Proof of Dehn's Theorem at Everything2 • Weisstein, Eric W.

WebHilbert's problems ranged greatly in topic and precision. Some of them are propounded precisely enough to enable a clear affirmative or negative answer, like the 3rd problem, which was the first to be solved, or the 8th problem (the Riemann hypothesis). For other problems, such as the 5th, experts have traditionally agreed on a single ... WebDec 22, 2014 · The Sydler theorem states that two polytopes in three-dimensional space are scissors equivalent if and only if they have equal volume and the same Dehn invariant, thus solving Hilbert's third problem in a very precise manner (cf. also Hilbert problems).
