give me an example for all of them

net – the pattern of a three-dimensional object in a flattened form

rectangular prism – a three-dimensional figure with 6 rectangular faces, 12 edges, and 8 vertices

surface area – the measure of the total area of the surface of a three-dimensional shape

Example: A rectangular prism has a net that can be laid out flat to show all its faces connected in a two-dimensional form. The surface area of the rectangular prism can be calculated by finding the area of each individual face and adding them all together.
