### Density of a Rectangular Piece of MetalPure gold has a density of \( 19,300 \, \rm{kg/m^3} \).A friend gives you as a gift a rectangular piece of metal with dimensions \( 10.0 \, \rm{mm} \times 20.0 \, \rm{mm} \times 30.0 \, \rm{mm} \) and a mass of \( 4.50 \times 10^{-2} \, \rm{kg} \).Your friend says it is pure gold. Which density do you derive for this rectangular piece of metal? And is it gold?Express your answer in kilograms per cubic meter.
