A rhombus prism has 6 faces. Any or all of them could be considered 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.
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.
