Building upon what we have.

I once heard water is the source of all life. So that seems like a great liquid to work with. It makes it nice that we can just turn on a tap to get it.

Since we have already done the hard work of creating the meter, we should build on that good work and use it to create our volume measurement.

My first thought is we can build a box 1m wide, 1m deep, and 1m tall (1m³).

🚨 Wait!

Without even constructing the box I can tell that is going to be a lot of water. Perhaps we should start smaller. Maybe only a 10th, and if you remember we already defined that as a decimeter.

Let's take the decimeter and create a box.

Now let's set the height, width, and depth to 1 decimeter or 1dm³.

That will work. Now for a name. We can pull an old measure name from the Greek archives. How about an old Greek measure no longer in use; litra or for us a liter. We are nearly finished.

Now we can apply our pattern from the meter.

Great job!

The really interesting part of this is the relationship between the meter. I imagine if we keep building off one another this relationship will prove helpful.

Now I'm curious how much does this liter weigh?
