What are polhedrons?
Polyhedrons are shapes with many faces
How do you find sum of a shape?
A shape does not have a sum. You can sum its angles, the lengths of its sides, the areas of its faces and so on. But the shape does not have a sum, in itself.
The sum of the areas of the lateral faces of a prism?
Perimeter of base*Length of prism.
What is the relationship among the vertices's faces and edges of polyhedrons?
If you add the vertices and Faces and subtract 2 from that number you get the number of edges. Vertices+Faces=Edges+2
Are Pyramids polyhedrons?
Yes, pyramids are considered polyhedrons because they are three-dimensional geometric shapes with flat polygonal faces. A pyramid has a polygonal base and triangular faces that converge at a single point called the apex. The number of triangular faces corresponds to the number of sides on the base polygon, making pyramids a specific type of polyhedron.
Are cones polyhedrons?
no because it has curved faces.
What are polhedrons?

Is it true that the faces of a polyhedrons are polygons?
yes
Why are cylinders and cones not considered to be polyhedrons?
Cylinders and cones are not considered polyhedrons because they do not have flat faces, which is a defining characteristic of polyhedrons. Polyhedrons are three-dimensional shapes made up of flat surfaces, while cylinders and cones have curved surfaces. Additionally, polyhedrons have straight edges where faces meet, whereas cylinders and cones have curved edges. Therefore, cylinders and cones are classified as curved surfaces rather than polyhedrons.
Which polyhedrons has more faces but less vertices?
An octahedron, for example. 8 faces, 6 vertices.
What is the sum of the areas of a polyhedron's faces?
Its total surface area.
How do you find sum of a shape?

6
Surface area of spatial figures?
It is the sum of the areas of each of its faces.
What is the surface area of this triangular pyramid?
It is the sum of the areas of its four faces.
What are the properties of polyhedrons?
Polyhedrons are three-dimensional geometric shapes with flat polygonal faces, straight edges, and vertices. They are characterized by their number of faces, vertices, and edges, which are related by Euler's formula: ( V - E + F = 2 ), where ( V ) is vertices, ( E ) is edges, and ( F ) is faces. Polyhedrons can be classified into regular (Platonic solids, where all faces are identical) and irregular types. Their faces can vary in shape, but they are always formed by connecting edges at vertices.
