There are hexagonal prisms and quadrangular pyramids with the same length of one edge. The sum of the lengths of all edges of a hexagonal prism is 81 meters (m), and all edges are the same length. Find the sum of the lengths of all the edges of the quadrangular pyramid, in meters (m), when all the edges of the quadrangular pyramid are the same length.
