multiplying the perimeter of the base by the height and adding the area of both bases.
sum of the area of its faces

The first answer works only for a prism, not for polyhedra in general.
the surface area
It is a face of the polyhedron
They are its faces
NO a cone is not a polyhedron as it has a curved surface. Similarly sphere and cylinders r 3D but not polyhedrons
Because that is how a polyhedron is defined.
Find the surface area of each face then add them together to give the total surface area.
Sum the areas of each face.
It is called the surface area.
False...
True.
The answer is TRUE.
the surface area
Its total surface area.
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.
0.0941 cubic units.
