#### Question from UPSC Prelims 2020 CSAT Paper

**Explanation : **

## Cubic millimeters water in grams

We know that, 1 cubic millimeters = (10)^-6 liters

Or 1 liter = 10^6

cubic millimeters

Now, Weight of 1 kg or 1000 grams = 10^6

cubic millimeters

Then, Weight of 0.1 grams = 10^2 or 100 cubic millimeters
