Twelve fathoms
Sand needed: 8*6*1.5 = 72 cubic feet
Two atmospheres is 67.8 feet of water.
Water pressure increases with depth due to the weight of the water above pushing down. At 20 feet, there is twice the amount of water above compared to 10 feet, resulting in greater pressure. Specifically, water pressure increases by approximately 0.43 pounds per square inch (psi) for every foot of depth, leading to a higher total pressure at greater depths. Thus, the pressure at 20 feet is greater than at 10 feet due to this cumulative weight of the water.
78 feet
72 feet is already linear as feet is linear so answer is 72

1,000atm is about 33,900 feet of water depth.
660 feet is the water proof depth.
It is 2250 cubic feet.
At 300 feet of water depth the pressure is about 130 psi
To cover 144 sq ft with soil to a depth of 6 inches, you would need 72 cubic feet of soil. This can be calculated by multiplying the area (144 sq ft) by the desired depth (6/12 ft) to get the volume in cubic feet.
35000 feet of altitude exerts more pressure on an object compared to 260 feet of water depth. This is because the pressure exerted by the atmosphere decreases as altitude increases, while the pressure exerted by water increases as depth increases.
Sand needed: 8*6*1.5 = 72 cubic feet
300 feet of sea water exerts a pressure of approximately 130 psi.
The depth of a quicksand pit can vary, but it is typically around 6-8 feet deep. This would be equivalent to approximately 72-96 inches in depth.
72 cubic feet
4 atmospheres is about 135.6 feet of water depth.
