Crown-Destiny

Crown#-1, Mass-1890g, Volume-180cm3, Density-10.5g/cm3
Crown#-2, Mass-486g, Volume-180cm3, Density-2.7g/cm3
Crown#-3, Mass-1404g, Volume-180cm3, Density-7.8g/cm3
Crown#-4, Mass-3474g, Volume-180cm3, Density-19.3g/cm3
Crown#-5, Mass-2034g, Volume-180cm3, Density-11.3g/cm3

Calculations: 1890g: 180cm3 = 10.5g/cm3
486g: 180cm3=0.48 g/cm3
1404g: 180cm3=7.8 g/cm3
3474g: 180cm3=19.3 g/cm3
2034g: 180cm3= 11.3 g/cm3

Answers to the questions

1) The first crown is made out of silver
The second crown is made out of aluminum
The third crown is made out of steel
The fourth crown is made out of gold
The fifth crown is made out of lead

2) The crown that is made out of pure gold is crown number four.

3) The first crown is silver because it matches the density of the silver on the “Density of Common Substances.”
The second crown is made out of aluminum because it matches the density of aluminum on the “Density of Common Substances.”
The third crown is made out of steel because it matches the density of the steel on the “Density of Common Substances”.
The fourth crown is made out of gold because it matches the density of the gold on the “Density of Common Substances”.
The fifth crown is made out of lead because it matches the density of the lead on the “Density of common Substances”.

4) I think that the crowns look the same because some of them could be just be coloured in paint
