The density of silver is 10.5 g/cm3. What is the mass (in kilograms) of a cube of silver that measures 0.64 m on each side?

I got 2752.512 kg but it says its wrong?


Sagot :

  • Density=10.5g/cm^3
  • Volume=(side)^3=(0.64)^3=0.2621m^3

Convert to cm^3

[tex]\\ \sf\longmapsto 0.2621(1000000)=262100cm^3[/tex]

Now

[tex]\boxed{\sf Density=\dfrac{Mass}{Volume}}[/tex]

[tex]\\ \sf\longmapsto Mass=Density\times Volume[/tex]

[tex]\\ \sf\longmapsto Mass=10.5(262100)[/tex]

[tex]\\ \sf\longmapsto Mass\approx 2752.512g[/tex]

[tex]\\ \sf\longmapsto Mass\approx2.7kg[/tex]
