Not sure what a lateral edge is. There are 50 edges in the base and another 50 sloped edges "going up" to the apex.
A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges. 18 base edges and 9 lateral edges
A heptagonal prism has 7 lateral edges. This is because a heptagonal prism consists of two heptagonal bases connected by vertical edges, and each vertex of the heptagonal base corresponds to a lateral edge. Since a heptagon has 7 sides, there are 7 lateral edges in total.
It has 9 edges, 6 vertices and 5 faces
It has 5 sides
a triangular prism has 5 sides.
There are 6 edges on a tetrahedron. The triangular base has 3, plus one for each lateral face.43 edges
There are 18 of them with 8 faces and 12 vertices
