What is the minimum oxygen quantity for three crew members?

Explanation:
The amount is determined by the per-person minimum multiplied by the number of crew. If each crew member requires 370 PSI to meet the minimum, three crew members need 370 × 3 = 1110 PSI. This is the smallest total that still provides enough oxygen for everyone. The other numbers would fall short for all three (900 and 1000), or exceed the minimum need (1200) but aren’t the smallest acceptable total.
