It is impossible to tell. You need to know a rectangular WHAT? A rectangular prism, a rectangular pyramid, a rectangular dipyramid, etc will all give different answers.

A triangular prism has three rectangular faces. In addition to these rectangular faces, it also has two triangular bases, making a total of five faces overall. The rectangular faces connect the corresponding edges of the triangular bases.
Yes, there are two pairs of parallel sides.
A cylinder is different because it is has no edges and a rectangular prism does. A cylinder has two faces and a rectangular prism has 6. A cylinder doesn't have any verticies and a rectangular prism has 8.
A pentagonal prism has two end faces of pentagons plus 5 rectangular faces between them; thus it has: 7 faces, 10 vertices and 15 edges.

A rectangular triangle is an oxymoron! A triangle cannot be rectangular and no rectangular shape can be a triangle. The two words contradict each other.
There are eight (8). Vertices are the corners where two edges meet.
A rectangular prism has six faces because it has 4 sides and two bases. It also has eight vertices and 12 edges.
the vertice's in a rectangular prism are located wherever two edges meet.
A triangular prism has five faces and nine edges. Two of the faces are triangular bases and the other three faces are rectangular.
Considering that any two edges that meet at 90 degrees are perpendicular, there are 3 per corner, giving a total of 24.
maybe it has 8 edges............ . Edges - as in corners? I make it nine. Edges as in faces? I make it five. A triangular prism has 5 edges * * * * * Edges are not corners! They are the "lines" where two faces meet. There are 9 edges in a triangular prism.
