can anyone find an answer to the following please:

[nm08]

I have created a container with water in it and labelled the container at different heights. (from 0 - 100ml)

5 pixels = 1ml

i now want to type in the command line: java water 50
so that the container is blue up to the number 50.

i am uncertain of how to calculate this so this works,

i am using the following:

g.setColor(Color.blue);
g.fillRect(140,60,25,600);
