Coordinates of vertices

I am sure I have done this before but I can't for the life of me 
remember how, and I can't find it in the manual. Some help would be much 
appreciated. I'd like to find the coordinates of the vertices of a 
truncated cube.

Whilst Vertices[cube] correctly gives me the coordinates of a cube 
Vertices[Truncate[Polyhedron[Cube]]] doesn't do what I want because 
Truncate[Polyhedron[... is a graphics object not a polyhedron object. So 
can I convert the graphics object into a polyhedron and use vertices, or 
work out the vertices some other way (for a cube this is trivial to do 
but for more complicated shapes this is much more tedious)

Thanks,

Peter
