give me an examples 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
1. Net example: A net of a cube consists of six squares connected by their edges to show how the cube unfolds into a flat shape.
2. Rectangular prism example: A cardboard box is a common example of a rectangular prism, with its six faces forming rectangles and all edges meeting at right angles.
3. Surface area example: The surface area of a rectangular prism can be calculated by finding the area of each face (2lw + 2wh + 2lh) and adding them together. For example, if a rectangular prism has length 3 cm, width 2 cm, and height 4 cm, the total surface area would be 52 cm².
