Density of mass

Question

Mass is 500g  Mass is perfect 2cm cube  What is the density?  Is it gold?

Answer 1

Density of gold is 19.3 g/cm³. Density (by the definition) is mass per unit of volume:

 

                         D = m/V                (D - density, m - mass, V - volume)

 

If one side of the cube is 2 cm, then the its volume is 2³ cm³ = 8 cm³. Thus

 

                              D = 500 g/8 cm³  = 62.5 g/cm³    - it is too heavy for gold.
