Explanation & Answer

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

mass = density x volume 

the volume of this bar is 5.6 cm x 14 cm x 30 cm = 2352 cm^3 

and we need to know the density of gold is19.3 g/cm^3 

therefore the mass of the bar is 19.3g/cm^3 x 2352 cm^3 = 45393.6 g = 45.4 kg

Please let me know if you need any clarification. I'm always happy to answer your questions.
