I think the difficulty of Archimedes is how to measure the volumn of the crown, not the weight. To measure its weight, just use a balance.
I remember the son of Caocao also used a boat to measure the weight of an elephant. Archimedes and him, who's earlier? It is a pity that son of Caocao didn't find the buoyance law, although he writes good poems.
