There are different formulae for different polyhedra and these depend on what information about the polyhedron is given.

That depends on what the shape of the faces of each side of the polyhedron is - since a ten-sided figure does not create a regular polyhedron, it is impossible to calculate its volume based simply on this information.
The formula is V-E+F=2 and it tells us that if we take the number of vertices a polyhedron has and subtract the number of edges and then add the number of faces, that result will always be 2.
No, F + V = E + 2That's Euler's polyhedron formula (or Theorem). For a normal 3-d polyhedron to exist it must conform to that equation.
The formula of volume
The volume of a triangle can be calculated with the formula: volume=1/2*length*width*height.
