a, b, c - length of edges of a base. H - height. The hexagonal prism has 8 faces, 18 edges, 12 vertices. Angles in hexagonal prism. The hexagonal right prism has in the base regular hexagon. The volume and the surface find in the same way as all prisms: V = A_bH, S = 2A_b +A_l. H - height, A_b - base area (hexagon), A_l - lateral surface area (sum of areas of rectangles).
