Abstract:Abstract. In the projective Cayley-Klein model the hyperbolic space H 3 of positive curvature is realized on the ideal domain of the Lobachevskii space. In this work the basic notions of the volumes theory of the space H 3 are introduced through invariants of the fundamental group of the space. In the orthogonal curvilinear coordinate system the volume formula of a finite orthogonal h-cone and some corollaries from it are proved.
