Final answer:
The pressure on the top lid of the chest buried under 4.00 meters of mud is 68,600 Pa.
Step-by-step explanation:
The pressure on the top lid of the chest can be calculated using the formula for pressure:
Pressure = density x g x height
where density is the density of the mud (1.75 x 10^3 kg/m^3), g is the acceleration due to gravity (9.8 m/s^2), and height is the height of the mud (4.00 m).
Plugging in the values, we get:
Pressure = (1.75 x 10^3 kg/m^3) x (9.8 m/s^2) x (4.00 m) = 68,600 Pa.
Therefore, the pressure on the top lid of the chest buried under 4.00 meters of mud is 68,600 Pa.
