Can a polyhedron have 10 faces,20 edges and 15 vertices?

Is it possible to have a polyhedron with any given number of faces?(Hint:Think of a pyramid).

Choose the correct answer The mean of the numbers obtained on throwing a die having written 1 on three faces, 2 on two faces and 5 on one face is

Using Euler's formula,find the number of faces if the number of vertices is 6 and the number of edges is 12.

Which of the following does not have a face-centred cubic lattice ?

In a unit cell, atoms (A) are present at all corner lattices, (B) are present at alternate faces and all edge centres. Atoms (C) are present at face centres left from (B) and one at each body diagonal at disntance of 1//4th of body diagonal from corner. Formula of given solid is

The number of triangles that can be formed with 10 points as vertices n of them being collinear, is 110. Then n is

In rolling a die . Suppose the second player got a six on the top face. Does it mean that the third player would not have a chance of getting a six on the top face?
