A decagonal prism has 12 faces, 30 edges, and 22 vertices. The two decagonal bases contribute 10 vertices each, while the lateral faces (10 rectangles) connect the corresponding vertices of the bases. Thus, the total number of vertices is 10 (top) + 10 (bottom) = 20, and with the 10 edges of the decagons and 10 vertical edges connecting them, you get 30 edges.
