Create a Unity script that stacks objects on top of a pallet

I need a simple script, which starts with a wood pallet base, an 3d asset (box, bag, container), and x, y z numbers, and assembles a bundle of x * y * z objects over the wood pallet base, respecting the object dimensions. For clarity: assemblepallet (base asset, to_be_piled_object, x y z), scales the wooden base and assembles a 3d stack of x * y * z elements on top of it. Tip if you can get a convincing plastic wrapping over the objects, or tie a rope, etc.
