A weather balloon contains $12.0\ \text{kg}$ of helium. When the balloon is at a height of $20\ \text{km}$, the pressure inside it is $6000\ \text{Pa}$ and the temperature is $216\ \text{K}$. Calculate the volume of the weather balloon at this height, correct to three significant figures.
- A$897\ \text{dm}^3$
- B$1790\ \text{dm}^3$
- C$897\ 000\ \text{dm}^3$
- D$1\ 790\ 000\ \text{dm}^3$
