    First one and last one are regular because all their sides have one line through them this they are the same. The second one is concaved on some axiom and is not a regular polyhedron

    and the third question is: using f+v=e+2 find the unknown number 1) faces:? vertices: 6 edges: 12 2) faces 5, vertices ?, edges 8 3) faces 7, vertices 10, edges ?

    The cross section is just what shape does the cut make so: Square, hexagon and triangle

    Just put the numbers into the equation and do the arithmetic for the thrir question

    You can just plug those numbers in, I know you can do that, we did it last time with the angles!

    I think the first cross section is a trapezoid

    faces:? vertices: 6 edges: 12 f + 6 = 12 + 2 2) faces 5, vertices ?, edges 8 5 + v = 8 + 2 3) faces 7, vertices 10, edges ? 7 + 10 = e + 2

    It might be a trapezoid, I can't see it too well, and yes those equations are correct, now solve! :)
