Odpowiedź:
[tex]8500\frac{kg}{m^{3}} = 8,5\frac{g}{cm^{3}}\\\\1,2\frac{g}{cm^{3}} = 1200\frac{kg}{m^{3}}[/tex]
Wyjaśnienie:
[tex]1 \ kg = 1000 \ g \ \ \rightarrow \ \ 1 \ g = \frac{1}{1000} \ kg\\\\1 \ m^{3} = 1 000 000 \ cm^{3} \ \ \rightarrow \ \ 1 \ cm^{3} =\frac{1}{1000000} \ m^{3}[/tex]
[tex]8500\frac{kg}{m^{3}} = 8500\cdot\frac{1000 \ g}{1000000 \ cm^{3}} = 8500\cdot\frac{1}{1000} \ \frac{g}{cm^{3}} = 8,5\frac{g}{cm^{3}}\\\\1,2\frac{g}{cm^{}} = 1,2\cdot\frac{\frac{1}{1000}kg}{\frac{1}{1000000}m^{3}} = 1,2\cdot1000 \ \frac{kg}{m^{3}} = 1200\frac{kg}{m^{3}}[/tex]
