Calculate the mass of a solid gold rectangular bar that has dimensions lwh = 4.60 cm ✕ 13.0 cm ✕ 30.0 cm. (The density of gold is 19.3 ✕ 10^{3} kg/m^{3}.)

Thank you for the opportunity to help you with your question!

lwh is the volume of the gold that is 1794 cm3 and 0.001794 m3

mass per volume is density so

mass= density * volume

=19.3* 10^3 * 0.001794

=34.6242 kg
