An example would be a cube.
A face
Net
2d, or two demensional
octagonal prism
3 demensional
A face
the 2 demensional is flat and the 3 demensional shape is like a cube(it is popped out).
Space-filling molecular model =)
Net
2d, or two demensional
No it is NOT a polygon, because polygons reffer to 2-demensional figures, however, a CUBE is three demensional.
octagonal prism
a stereomicroscope is a microscope that produces a three-demensional image
3 demensional
Triangle is a shape with three sides.
A pyramid
