Each and every prism has two parallel congruent bases. It is the shape of these bases that give the name to the prism: a pentagonal prism has pentagons (not necessarily regular) for its bases.
It has 4 bases.
A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges.
A rhombus has 4 vertices, therefore a rhombic prism has 4 x 2 = 8 vertices.
a triangular prism has to triangular bases while a rectangular prism has a rectangle as the bases.
It depends on what kind of prism you mean. For example, a rectangular prism has 6 bases and a triangular prism has 5 bases. A triangular prism only has two bases.
A triangular prism has 2 bases on it!
a pentagonal prism has 2 bases
Each and every prism has two parallel congruent bases. It is the shape of these bases that give the name to the prism: a pentagonal prism has pentagons (not necessarily regular) for its bases.
A heptagonal prism has two 7-sided bases.
It has 4 bases.
It has 5 bases
None. By definition, a triangular prism has triangular bases. If it had circular bases it would be a circular prism (cylinder).
A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges.
A rhombus has 4 vertices, therefore a rhombic prism has 4 x 2 = 8 vertices.
It depends on the prism but cones will always have one.
