Two meter sticks taped together LOL.
300m3
Well a bookcase or chair would be a perfect answer
30 cubic meters
If you multiply length x width x depth, you will get the volume - which in this case will be in cubic meters. Which is 54. Which is the same as 54ml :)
The pressure on the object can be calculated using the formula P = ρgh, where P is the pressure, ρ is the density of the fluid, g is the acceleration due to gravity, and h is the depth. Given that the object is at a depth of 30 meters and the area is 9 sq cm, additional information about the fluid and object is needed to calculate the pressure.
A hole does not have dirt!
Because it increases. As you descend in the sea each 10 meters of water above you weighs as much as the whole of Earth's atmosphere as experience at Sea Level. Thus at 10 meters depth in the sea you experience a pressure of 2 atmospheres. At 20 meters 3 atmospheres At 30 meters 4 atmospheres At 100 meters 11 atmospheres At 1000 meters 101 atmospheres.
You need 1.35 cubic meters for each centimeter deep.
A person can go to a plane after swimming in a 2M deep pool because the pressure is not too much.
half of the ocean is 900,999,999 thousand meters deep and 400,000,000,000 meters wide
7.5 cubic meters.
10.20 meters in depth

There is greater pressure the deeper you go in water. So if you go too deep, the pressure in the human lungs will be so great and too much that the persons lungs will collapse.
At 30 meters depth in salt water, a diver will experience a pressure of approximately 4 atmospheres or 4 times the pressure at the surface. This is because water exerts 1 atmosphere of pressure for every 10 meters of depth.
