Each edge of the polyhedron is shared between exactly one triangle and exactly one square, as can be inferred from the question statement. Thus, given six squares, there are 24 edges ( 6 × 4 ), and thus eight triangles ( 24 ÷ 3 ). The polyhedron is called a cuboctahedron. Thanks! fallshigh73.cfsfaa.org
