Answer :
[tex]l-liter\\mm-milimeter\\dm-decimeter\\--------------------\\deci\ (d)=0.1\ of\ some\ value\\milli\ (m)=0.001\ of\ some\ value\\-----------------\\therefore\ 1dm=100mm\\-----------------\\1l=1dm^3\\1dm^3=(100mm)^3=100^3mm^3=1,000,000mm^3\\---------------------\\Your\ a\ question:\\\\5.5l=5.5dm^3=5.5\cdot1,000,000mm^3=5,500,000mm^3[/tex]
[tex]Scientific\ notation:\\\\5,\underbrace{500,000}_{\leftarrow6}mm^3=5.5\cdot10^6mm^3[/tex]
