Assuming that a 3D parallelogram is a parallelepiped, it must have three sets of quartets of parallel lines.
In a 3D world with 6 sides it is a cube.
It has 6 sides and on the dice you can see that all the opposite sides equal 7. So this a good question but the 3D cube can be used in many ways such as jobs and math.
A Cuboid which is a 3D square.
A pyramid. Triangular base and three connected sides equal a pyramid.
If it's 3D then it could be a rectangular pyramid.
A cube (If you're talking about a 3D shape)!
About 26 sides, and 24 corners.

In a virtual 3D environment a cylinder can have as many sides as it take for it to look convincing. Though for optimization purposes the fewer the better.
12 (a dodecahedron)
