A square has only one face and, if that is a base, then it has 1.
None!
A square pyramid has 1 square base and 4 triangle-shaped sides.
Neither have square bases, both have circular bases.
The base is the bottom, so a square-based pyramid has ONE base.
A square based pyramid has 5 vertices, 8 edges and 5 faces
5. one for the square bottom, and one for each side coming out from the square
The shape that has 2 square bases and 4 square faces is a square prism, also known as a cuboid or square bipyramid. It features two parallel square faces (the bases) and four rectangular faces connecting the corresponding edges of the bases. In a strict sense, it can also be referred to as a square-based prism if considering the bases as squares. This solid is a type of polyhedron with a total of 8 faces.
Main difference is that square pyramids have square bases, cones have circular bases. For this reason, they're calculated differently.
If a cube is considered as a square prism, then any pair of opposite sides may be considered its bases. In that case, there are four sides that join the two bases.
Cubes are prisms that have squares as bases and the height is the same as the edges. A square prism has square bases, top and bottom, and parallelograms as sides. A square pyramid has a square base and triangles for the vertical sides.
