What is a 3D shape with 6 regular faces?

A 3D shape with six regular faces is called a cuboctahedron. Each face of a cuboctahedron is a regular polygon, specifically squares and equilateral triangles. In total, it has 12 edges and 8 vertices, making it a type of Archimedean solid. Another example of a shape with six regular faces is a cube, where all faces are squares.
