A square based pyramid is a 3-d object. It does not have a 2-d name!
Just the one square flat face.
A flat (2D) shape triangle has 3 straight edges. A triangular pyramid has 6 straight edges. A square pyramid has 8 straight edges. (Note, some vertical edges have already been counted as you move from one face to the next.)
3D = Pyramid 2D = Triangle
Yes. Just like a square is 2D.
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.
a 2d square * * * * * A square has four sides. A side is not a face. A tetrahedron (triangular pyramid) has four faces.

It is a 3 dimensional shape
Just the one square flat face.
Since the square is a 2D shape, it only has one face.
It is NEITHER. A SQUARE is a PLAIN 2-dimensional figure . A PRISM & a PYRAMID are 3-dimensional objects.

No. A pyramid is a three-dimensional shape.
A prism is 3d and a pyramid is in 2d
a pyramid is a 3D shape :)
