Answer:

  2500 kg/m³

Explanation:

The density is ...

   (107 g)/((12.2 cm)(3.7 cm)(0.95 cm)) = 107/42.883 g/cm³ ≈ 2.5 g/cm³

In kg/m³, the density is ...

  (2.5 g/cm³)×(1 kg/(1000 g))×(100 cm/m)³ = 2500 kg/m³

The conversion from CGS to MKS units of density is done using the usual method of units conversion. The conversion factor multipliers each change the units without changing the value, because their numerator is equal to the denominator.
