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.
solid with 2 edges is a cylinder
That depends on the kind of polyhedron.There are five kinds of regular polyhedra (all edges of equal length).Tetrahedron (four-sided pyramid) has 6 edgesHexahedron (cube) has 12 edgesOctahedron (eight-sided solid) has 12 edgesDodecahedron (12-sided solid) has 30 edgesIcosahedron (20-sided solid) has 30 edgesIt is also possible to have a polyhedron that is not regular, with almost any number of sides and edges.
A hexahedron, also known as a parallelepiped.
A rectangular prism.
hexahedron
If a rectangular solid is a cuboid, the answer is 12.
A rectangular prism (or cuboid) has 12 edges.
Rectangular prism
A cube.
None.
A cube.
It is a hexahedron
Cube or rectangular prism.
How about a cuboid which has 8 vertices, 12 edges and 6 faces.
An octohedron
umm....a square??
