Answer
The volume 1.3 $µm^{3}$ of the particle can be expressed as 1.3 x $10^{-15}$ liters.
Work Step by Step
1 - Convert volume from $µm^{3}$ to $m^{3}$.
we know that 1µm = $10^{-6}$ m, therefore
1.3 $µm^{3}$ = 1.3 x $(10^{-6})^{3}$ $m^{3}$
1.3 $µm^{3}$ = 1.3 x $10^{-18}$ $m^{3}$
2- Convert the volume from $m^{3}$ to liters.
We know that 1 liter = 1 $dm^{3}$, and 1$m^{3}$ =$10^{3}$ $dm^{3}$.
1.3 x $10^{-18}$ $m^{3}$ = 1.3 x $10^{-18}$ x $10^{3}$ $dm^{3}$
1.3 x $10^{-18}$ $m^{3}$ = 1.3 x $10^{-15}$ $dm^{3}$
1.3 x $10^{-15}$ $dm^{3}$ = 1.3 x $10^{-15}$ liters
So the volume 1.3 $µm^{3}$ of the particle can be expressed as 1.3 x $10^{-15}$ liters
