How to do same with cube as cylinder(d1,d2,h)

I want cube which has top of 5x5 and bottom 8x8 and height of 15.

With cylinder I can do this simply cylinder(d1=8, d2=5 h=15) but how do I do this with cube? With polyhedron and hard thinking could achieve that, but not really useful, I think.

you can use either hull() to do this, e.g.

hull(){
   cube([8,8,0.1]);
   translate([1.5,1.5,14.9])cube([5,5,0.1]);
}

or just use cylinder with $fn=4, something like:

rotate(45)cylinder(d1=8*sqrt(2), d2=5*sqrt(2), h=15,$fn=4);
