A net is a 2D representation of a 3D shape
in 2D, a heptagon in 3D, a heptahedron
no solid figure has only face the only shapes that has 1 face is 2d shapes
A flat piece of paper is 2D. A cube is 3D. Therefore the drawing of the cube is a representation.

A projection is a 2 dimensional representation of a solid figure. See related link.

You cannot have a 2d pyramid - whether or not it is square based. The 2d cross section will depend on the plane of the cross section.
three
It is a 2D net that represents a 3D figure
Topography is a 2D representation of geography, relief is 3D, making it easier to visualize relative elevations.
a solid
no solid figure has only face the only shapes that has 1 face is 2d shapes
it is same as surface and volume ! a plane angle is 2D and solid angle is 3D
No because it is flat 2d shape with 4 equal sides
