Resizing a 3d(or not) image in flash professional CS6.

Question

I need some help with a project I am working on.
I am looking to create a simple user menu where you would input 3 values. Width, Length and Height (The scale would be fairly simple W 0-19, H 0-23 and L 0-31. So limited)
These X,Y and Z values would then cause a image of a cube in that proportion to be displayed on a simple grid. Also flash would output a price using an equation using the inputted numbers.
I think I will be fine with the actionscript for the equation but I am at a bit of a loss of how to deal with the visuals? Do I draw multiple separate images and call them up individually or is there a way to manipulate this (apparent 3d image) using action script referencing the outcome of the equation.
I dont have much experience with manipulating 3D with flash. In this video I can see how to create a 3d box:

But could I then manipulate this using actionscript?
Or do I need to use a 3d package such as alterniva 3d?
There must be a simpler way? Any help is really appreciated and if completed i will post results here for everyone.
Cheers

Away3D, Alternativa3D, Flare3D, they're all fine. If you're doing it for a commercial basis you'll need to consult the EULA of any specific framework but here's a simple example of Away3D in action (half way down the page is a cube):

Not bad for only needing this much code:

All engines will require some kind of "set up" and then you can add things in, primitives like cubes, spheres, etc. Then lighting, materials, etc.
The line of code that made that cube was very approachable:
// create cube
var cube:Cube = new Cube({width:200,height:100,depth:300,bothsides:true});
// add to previously created scene (in link above)
view.scene.addChild(cube);
// Set one of the cubeMaterials to a partially transparent white material
cube.cubeMaterials.left = new ColorMaterial(0xffffff,{alpha:.3});
That's pretty easy.
