There are 300 cm in 3 meters
15 cm equals 0.15 meters. Accordingly, the volume is 300 multiplied by 0.15. The result is 45 cubic meters.
At a depth of 300 meters in water, the pressure can be calculated using the formula: pressure = depth × density of water × gravitational acceleration. The density of seawater is approximately 1,025 kg/m³, and gravitational acceleration is about 9.81 m/s². Therefore, the pressure at 300 meters is around 3,000 kilopascals (kPa) or 30 times atmospheric pressure, which is roughly equivalent to 30 bar.
300 meters?
A barometer is a device for measuring atmospheric pressure - NOT distance or depth !

One atmosphere of pressure is equal to the pressure at sea level. Therefore, 100 atmospheres would be roughly equivalent to the pressure experienced at a depth of about 3,000 feet (914 meters) underwater.
3,000 miles is 4,828 kilometers or 15,840,000 feet.
406 meters / 1,332.02 feet of water depth has a pressure of about 39.3 atmospheres or 577.6 psi.
The diameter of Mount Vesuvius is 6 kilometres.
300 meters?
Up to 100 meters which is over 300 feet deep.
300 ft = 91.44 meters (rounded)

If you mean "Ho deep can people DIVE", the limit for commercial divers is between 100 and 200 meters. There have been, however, experiments with people in pressure chambers, simulating VERY deep dives. They exceeded 600 meters.
