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.
Well, honey, to find the surface area of a polyhedron, you gotta calculate the sum of the areas of all its faces. It's like wrapping a present - you gotta measure each side to know how much paper you need. So, grab your ruler, add up those face areas, and voilà, you've got the surface area of that geometric beast.

What is The sum of the areas of a polyhedron's faces is?
the surface area
What is a flat surface of the polyhedron called?
It is a face of the polyhedron
What is a flat surface of a polyhedron called?
They are its faces
Is a cone a polyhedron?
NO a cone is not a polyhedron as it has a curved surface. Similarly sphere and cylinders r 3D but not polyhedrons
Why is a three dimensional figure with curved surface not a polyhedron?
Because that is how a polyhedron is defined.
How can the surface area of a polyhedron be found?
Find the surface area of each face then add them together to give the total surface area.
The surface area of a polyhedron is found by?
Sum the areas of each face.
What is the flat surface of polyhedron called?
It is called the surface area.
In finding the surface area it is helpful to separate the polyhedron's surface area into the base area and the height?
False...
In finding the surface area it is helpful to seperate the polyhedron's surface area into the base area and the lateral area?
True.
In finding the surface area it is helpful to separate the polyhedron's surface area into the base area and the lateral area?
The answer is TRUE.
What is The sum of the areas of a polyhedron's faces is?
the surface area
What is the sum of the areas of a polyhedron's faces?
Its total surface area.
How can you find the surface area of a polyhedron?
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.
What is the upper limit for the volume of a polyhedron with surface area 1?
0.0941 cubic units.
To calculate the surface area of any polyhedron you find the area of the base then multiply that value by the number of faces?
False
