For this case we have:
Note: Milliliter is a unit of volume. It is not possible to convert distance units into volume units.
We must convert the length 0.13 meters to millimeters.
By definition, 1 meter equals 1000 millimeters. That is to say:
[tex]1m = 1000mm[/tex]
Then, applying the rule of three we have:
1m ------------> 1000mm
0.13m --------> x
Where x represents the length of the marker in millimeters.
Resolving:
[tex]x = \frac {(0.13 * 1000)} {1}[/tex]
[tex]x = \frac {130} {1}\\x = 130[/tex]
Thus, the marker measures 130 millimeters long
Answer:
130 millimeters
