[tex]1 \frac{g}{ {cm}^{3} } = \frac{ \frac{1kg}{1000} }{ \frac{1 {m}^{3} }{1000000} } = 1000 \frac{kg}{ {m}^{3} } \\ \\ \: folosind \: regula \: de \: 3 \: simpla \\ \\ 1\frac{g}{ {cm}^{3} } ..............1000 \frac{kg}{ {m}^{3} } \\ \\ x \frac{g}{ {cm}^{3} } ...............100 \frac{kg}{ {m}^{3} } \\ \\ x \frac{g}{ {cm}^{3} } = 1 \frac{g}{ {cm}^{3} } \times 100 \frac{kg}{ {m}^{3} } \div \\ \\ \div 1000 \frac{kg}{ {m}^{3} } \\ \\ deci \: x = 0.1 \frac{g}{ {cm}^{3} } [/tex]
Sper ca e bine nu sunt asa de bun la fizica.
