A shape with 18 edges is a type of polyhedron known as a triaugmented triangular prism. This geometric figure consists of two triangular bases and three rectangular lateral faces, along with additional triangular faces that augment the prism. Another example of a shape with 18 edges is a dodecahedron combined with additional triangular pyramids, but the triaugmented triangular prism is the most straightforward example.
