that's a statement, but if you ment to say are the... then yes
Face
cross section
There is no standard formula since a polyhedron can have a number of different shapes. A hexahendron, for example, can be a cuboid (6 rectangular faces) or a triangular dipyramid (6 triangular faces) or others. The number of different shapes increases rapidly as the number of sides (which determines the name) increases. The only solution is to calculate the area of each face and add them together.
A net is an arrangement of polygons, joined edge-to-edge, that when folded up, form the surface of a polyhedron.
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.
