A gas in an engine carries out work on a piston whose cross-sectional area is $80\,\text{cm}^2$. The piston is under a constant pressure of $4.6 \times 10^5\,\text{Pa}$. What amount of work is done by the gas on the piston as it travels a distance of $25\,\text{cm}$?
- A$9.2 \times 10^2\,\text{J}$
- B$9.2 \times 10^4\,\text{J}$
- C$9.2 \times 10^6\,\text{J}$
- D$9.2 \times 10^8\,\text{J}$
