What is Density?
The Density of a material is the mass per unit volume
say the mass is m kg
and the volume is v cm^3
Then the density is
Density = mass/volume
Given data
Mass = 252g gram
volume = 30 cm^3
Hence the density can be calculated as
Density = 252/30
Density = 8.4 g/cm^3
From the value, this corresponds to the density of Brass
