$1\text{m}^3= 1\, 000 \text{dm}^3 \\ 1\text{dm}^3 = 1\, 000\text{cm}^3 \\ 7,268\text{m}^3 =7\,268\text{dm}^3 \\ 4,351\text{dm}^3 = 4\,351\text{cm}^3 \\ 0,5\text{m}^3 = 500\text{dm}^3 \\ 0,2\text{dm}^3 = 200\text{cm}^3 \\ 3\text{m}^3 \, 2\text{dm}^3 = 3\,000 \text{dm}^3 + 2 \text{dm}^3 =3\,002\text{dm}^3 \\ 1\text{dm}^3 \, 9\text{cm}^3 = 1 \, 000 \text{cm}^3 + 9 \text{cm}^3 = 3\, 009\text{cm}^3$
