A triangular prism has 3 sides on each base (2) and 3 on the lengths of the prism therefore it has 9 edges.
It has 11. There are the 10 sides (decagonal) and then the base. So 11 total.
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.
5 sides 9 edges and 6 vertices
A heptagonal prism is a prism with a heptagon (7-sided polygon) as its base. It has 14 faces (2 heptagons and 12 rectangles), 20 vertices (2 at each corner of the heptagon and 2 at each corner of the rectangles), and 28 edges (7 edges on each heptagon base and 12 edges around the sides connecting the corresponding vertices of the base and top heptagon).
A triangular prism has 3 sides on each base (2) and 3 on the lengths of the prism therefore it has 9 edges.
A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges.
A hexagonal prism has 8 sides, 12 vertices, and 18 edges.
8 edges 6 sides
Sides = Faces: 9 Edges: 21.
It has 11. There are the 10 sides (decagonal) and then the base. So 11 total.
It has 5 sides
a triangular prism has 5 sides.
9 edges
It has 5 sides
