There is no simple shape that has exactly 4 square sides.
A shape that has exactly 4 sides, 2 right angles and one pair of parallel sides is a rectangle. ~T
No 3D shape with FLAT SIDES has exactly 3 faces. 4 is the minimum.
Square
Assuming that each vertex is used to connect exactly two sides, all two-dimensional shapes will have the same number of sides as vertices. So a shape with 4 sides will have 4 vertices and a shape with 3 sides will have 3 vertices. Think of a square (4 sides, 4 vertices) and a triangle (3 sides, 3 vertices).
