This shape is a prism but its top and base do not have right angles in the shape. This is not a right rectangular prism.

This shape is not a prism. Neither it has rectangles in top and bottom nor there are any right angles in them. This is also not a right rectangular prism.
Net of a right rectangular prism:
The net of a 3D object shows the faces of that object when it is opened flat. We can form a right rectangular prism using its net as shown below as each face of the net is a rectangle which has right angles into it.
