Find the surface area of each face then add them together to give the total surface area.
A polyhedron is a closed figure with several (planar) sides, and all its sides are planar. A non polyhedron does not have these properties, maybe it is not closed, maybe one or more of the sides is a curved surface. In some branches of topology the sides of a polyhedron cannot intersect each other.
that's a statement, but if you ment to say are the... then yes
cross section
A polyhedron can have any number of faces 4 or higher.
Each surface of a polyhedron is called a face.
It is a face of the polyhedron
It is called the surface area.
It is called a face of the polyhedron.
Its surface, would you believe!
They are its faces
Sum the areas of each face.
Add up the surface area of each of the polygonal faces. There may be a short cut available if it is a regular polyhedron so that all the polygons are the same.
Find the surface area of each face then add them together to give the total surface area.
A polyhedron is a three dimensional figure made up of sides called faces, where each face is a polygon.
A non polyhedron does not have these properties, maybe it is not closed, maybe one or more of the sides is a curved surface. In some branches of topology the sides of a polyhedron cannot intersect each other.http://wiki.answers.com/What_is_the_difference_between_a_polyhedron_and_a_non_polyhedron#ixzz185DDOyd9
In normal usage "polyhedron" refers to solids whose edges are straight lines, not curves, so a strict answer would be: there is no such polyhedron.
