Trapezoid is 3D. The shadow of this shape is called Trapezium.
6 edges.
A 3D trapezoid, typically referred to as a trapezoidal prism, has 8 vertices. This shape consists of two parallel trapezoidal bases and four rectangular lateral faces connecting the corresponding edges of the bases. Each trapezoidal base has four vertices, resulting in a total of 8 vertices for the entire prism.
An 3d trapezoid
I believe it would have nine edges.
No corners and two edges !
A pentagonal prism will have 15 edges.
A trapezium has 1 face, 4 edges and 4 vertices.
