The volume of a piece of metal of mass 6g is 15cm cube. What is the density of the metal piece

Density is defined as the mass per unit volume. Therefore, to find the density of the metal piece, we divide the mass by the volume.

Given:
Mass = 6g
Volume = 15cm³

Density = Mass / Volume
Density = 6g / 15cm³

Therefore, the density of the metal piece is 0.4 g/cm³.
