A rectangular prism and a cube have 6 faces and 12 edges.
It is a hexahedron
It has 6 faces, 12 edges and 8 vertices
Any solid object with six faces is a hexahedron. A regular hexahedron (with 12 edges) is a cube where all the faces are squares An irregular hexahedron (with 12 edges) is a cuboid where two faces are equal squares and four are equal rectangles.
How about a cuboid which has 8 vertices, 12 edges and 6 faces.
WHAT IS A SOLID WITH TWELVE faces and 30 edgesis a dodecahedron.
A cube has 6 faces and 12 edges.
A rectangular prism.
2 solid shapes together have 8 faces, 12 edges 8 vertices
