This is probably about Euler's formula V - E + F = 2,
where V is the number of vertices, E he number of edges and F the number of faces.
Example: a cube has 6 faces (F = 6) and 8 vertices (V = 8). So the formula tells us that
8 - E + 6 = 2, and so E = 12. Yes, a cube has 12 edges.
Euler's formula only works for standard polyhedra, not unusual things like star polyhedra.

What is a polyhedron with five faces and a square base called?
A polyhedron can have any number of faces 4 or higher.
How do you calculate the median?
by arranging them in order counting the number of appearance and take the middle number or if the middle numbers are two you add and divide by two
What is the least number of faces that a polyhedron can have?
4
What is the formula of surface area of a polyhedron?
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.
What is the difference between a polyhedron and a non polyhedron?
A polyhedron is a three-dimensional solid with flat faces, straight edges, and sharp corners, while a non-polyhedron does not have these characteristics. Polyhedra are made up of polygons that enclose a single region of space, while non-polyhedra may have curved faces or intersecting edges. In mathematical terms, a polyhedron satisfies Euler's formula (V - E + F = 2), where V is the number of vertices, E is the number of edges, and F is the number of faces, while a non-polyhedron does not.
What is the largest polyhedron?
There is no such thing. The number of sides, as well as the area can be increased without limit.

If you know the numbers of faces and vertices in a polyhedron how can you calculate the number of edges with out counting them?
the is a pattern example a rectangular prism has 6 faces , 8 vertices and 12 edges. the pattern is add 2 then add 4 so to calculate you should first find the pattern or if you need more help go to www.math.com.
What is the term for recognizing groups of numbers without counting - such as on a die?
To subitize is to recognize the number in a group without counting.
