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.
The tetrahedron, consisting of four regular triangles.

square-based pyramid
solid with 2 edges is a cylinder
A triangular based pyramid seems to fit the description which has 4 faces, 6 edges and 4 vertices
The Johnson Solid J89, named Hebesphenomegacorona, has21 faces, of which 18 are triangles and 3 are squares.It also has 33 edges and 14 vertices.
It is a solid shape with six faces. There are seven topologically distinct convex shapes and three concave ones. The faces can be triangles, quadrilaterals or pentagonal and the number of edges can range from 9 to 12. The number of vertices is 4 fewer than the number of edges.
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.
