Break a 5x5 cube

[Kore]

Alright so I have a pick that breaks a 5x5 cube and I want it to drop the items in block they were at. how would this be possible.

P.S. I have the coords and id stored in a variable

[opssemnik]

Block.blocksList[id].dropBlockAsItem(par1World, x, y, z, par1World.getBlockId(x, y, z), metadata);

par1World.setBlock(x, y, z, 0);

Obs: 0 its the air block, it dosent craft and im using for my mod.
