There would be 8 faces. Each square pyramid has 1 square face (its base) and 4 triangular faces. When you glue the squares together, you get a new polyhedron with 8 faces.
Yes. A square consists of two pairs of parallel lines!
There are two faces on a square (front and back.) There are six faces on a cube.
There are many such shapes, not just two. Here are some:A nonagonal pyramidAn octagonal prismA square anti-prism (two square faces, with triangles between them)A decahedronA pentagonal bipyramid (two pentagonal pyramids stuck together at their pentagonal faces).Each one is known as a decahedron (plural decahedra).
Two. 4 faces are triangles and the base is a square.
An octahedron formed by joining together (base-to-base) two square-based pyramids.
One. A square is a two dimensional image.

Two or zero. A cuboid can have 6 rectangular faces; or 4 rectangular faces with 2 square faces on either end
A square prism (a cuboid with at least two square faces at its ends).
A face is a flat surface, like the front or top of a box. If you look at a square you will see that there are two sides so there are two faces.
