Yes. I think of an edge as a line. The edges meet at vertices, and the faces meet at edges.
were two or more faces of a solid figure

Any solid object with six faces is a hexahedron. A regular hexahedron (with 12 edges) is a cube where all the faces are squares An irregular hexahedron (with 12 edges) is a cuboid where two faces are equal squares and four are equal rectangles.
A solid is a 3-D object in which you can see all of the faces, edges, and vertices. A two dimensional figure is on paper and you cannot hold it in your hands.
A solid figure with nine edges is a triangular prism. This shape consists of two triangular bases and three rectangular lateral faces. The edges include three edges from each triangular base and three connecting edges between the bases, totaling nine edges.
A solid figure with nine edges is known as a triangular prism. It consists of two triangular bases connected by three rectangular faces, resulting in a total of nine edges: three edges from each triangular base and three edges connecting the corresponding vertices of the triangles.
