I’m sorry, but this question was copied from elsewhere; my calculation results do not match the given answer. I kindly ask everyone to share their calculation steps. Since I’ve seen that many users with higher levels have results that match the answer provided in the question, or have provided different answers, I hope you can offer some guidance. Let’s learn and discuss together. The quality of this question isn’t very good, so please forgive me! Answer: B. However, my own calculation gave a result of C, namely 300 M3 (10*3.0 = V*0.1, so V = 300 M3). This question is not well formulated; if atmospheric pressure is taken as 101325 Pa, the result is 296 M3, making option D closer to the correct value. The person who calculated 310 M3 provided an explanation for this, based on certain mathematical principles
