An artist creates a solid sculpture made from 9.40 kg of iron. She wishes to create an identical sculpture, using the same mold used to make the original, out of solid silver. What is themass (in kg) of the silver sculpture? (The density of iron is 7.86 x 10° kg/m³, and that of silver is 10,50 x 10° ka/m3.)
