The Euler characteristic indicates that such a solid does not exist.
Assuming that a solid triangle is a tetrahedron, the answer is: faces: 4 edges: 6 vertices: 4
There is no solid figure with only four edges. The smallest solid figure is the tetrahedron, made up of four triangular faces, but it has six edges.
tetrahedron
A tetrahedron is a solid figure with 6 edges. There's no such thing as solid edges. A tetrahedron is a triangular pyramid, with 4 vertices, 6 edges and 4 triangular faces. In a regular tetrahedron (the first Platonic solid) all triangles are equilateral.
A solid shape with 8 edges is known as a quadrilateral prism or a square prism, which has 8 edges in total (4 from the top face and 4 from the bottom face). Additionally, a triangular prism also has 9 edges, but it does not fit the criteria. Thus, the primary solid shape with exactly 8 edges is the square prism.
