Answer:
The pressure at this depth is 
.
Explanation:
According to the statement, the uncompressed fluid stands at atmospheric pressure. By Boyle's Law we have the following expression:
(1)
Where:
- Initial and final volume.
- Initial and final pressure.
If we know that 
, then the pressure ratio is:
If 
, then the final pressure of the gas is:
The pressure at this depth is .
