Hello, Lilianna,
We need two conversion factors:
- There are 1000ml per liter (1000ml/L)
- There are 100 cm per meter (100cm/meter)
Now use these to exchange the units, Note how the units cancel and how we're left with ml/meter - the target unit.
(29.7 L/cm)*(1000ml/L)*(100cm/meter) = 2.97x106 ml/meter
