The density of the block is 0.5 g/cm³ and the mass is 12 g.
The volume of the block is calculated as follows;
V = Lwh
V = 2 x 2 x 6 = 24 cm³
This is the fraction of the block submerged in water
S.G = 3.0cm / 6.0 cm = 0.5
Density of the bock is calculated as follows;
[tex]S.G = \frac{\rho _{block}}{\rho_{water}} \\\\0.5 = \frac{\rho _{block}}{1} \\\\\rho _{block} = 0.5 \ g/cm^3[/tex]
m = 0.5 g/cm³ x 24 cm³
m = 12 g.
