=================================================
Portando tutto a m³ in ordine decrescente:
1°) $0,078\,hm^3 = 0,078×100^3 = 78000\,m^3;$
2°) $6,9\,dam^3 =6,9×10^3 = 6900\,m^3;$
3°) $6,8\,m^3;$
4°) $150\,dm^3 = 150×10^{-3} = 0,15\,m^3;$
5°) $2459\,cm^3 = 2459×100^{-3} = 0,002459\,m^3\quad(= 2,459×10^{-3}\,m^3).$
