The shape described is a triangular prism.
triangular-based prism
An right equilateral triangular prism.
No. A triangle is a two-dimensional polygon (flat figure). It has sides that consist of three line segments, with an interior area. Only a three-dimensional form (polyhedron) can have faces. Triangles serve as faces for any number of polyhedrons, such as pyramids.
a cylinder
It could be a rectangle-based pyramid.
A square pyramid
The shape described is a triangular prism.
a rectangle
There are 2 triangle base faces, and 3 rectangle faces. 5 total faces.
None.
Triangle
An octahedron is a three-dimensional geometric shape with eight faces, each of which is an equilateral triangle. It is a polyhedron with eight vertices and 12 edges.
A triangular prism.
A rectangle is a two-dimensional shape, so it doesn't have faces in the way that three dimensional shapes have. A rectangle has four edges and four corners.
One - a rectangle is a flat shape - not a three dimensional object !
