There are 10,485,760 edges.
The general formula is d*2^(d-1) for d-dimensional space.
3 dimensional is a cube. it has 8 edges
A 3 dimensional pentagon has 15 edges
Number of sides of a hypercube depends on the level. A point is a hypercube of dimension zero. If one moves this point one unit length, it will sweep out a line segment, which is a unit hypercube of dimension one. If one moves this line segment its length in a perpendicular direction from itself; it sweeps out a two-dimensional square. If one moves the square one unit length in the direction perpendicular to the plane it lies on, it will generate a three-dimensional cube. This can be generalized to any number of dimensions. For example, if one moves the cube one unit length into the fourth dimension, it generates a 4-dimensional unit hypercube (a unit tesseract). You can research polytopes for many examples.

I don't think there's a three dimensional rectangle, and if the two dimensional triangle exists in three dimensional space, it would have strange properties because it only has 4 edges. There however, a three dimensional rectangular prism. It has 12 edges.
A three dimensional triangle is also known as a pyramid. In a triagonal pyramid, there are six edges and four corners.
A rhombus is a two dimensional figure while the concept of {faces, vertices and edges} is relevant to 3-dimensional shapes.
3 corners (vertices) and 3 edges (sides).
It has 12 edges... there is a Wikipedia page on the shape - including a picture, and dimensional data.
