Izv. Math. 66, No. 2, 377-391 (2002); translation from Izv. Ross. Akad. Nauk, Ser. Mat. 66, No. 2, 159-172 (2002).
In this paper for polyhedra in general position and with a given combinatorial structure the author proposes an algorithm for finding all their metric characteristics, namely, their volumes, dihedral angles and diagonals, from the lengths of their edges. In this way he develops a new line of geometric investigation, which, in analogy with the well-known term “solution of a triangle”, can be called “solution of a polyhedron”.
