A rectangular container having base area of 1.5 m2 and length 0.9 m is floating in water with the open end downwards. If the difference in water levels inside and outside the container is 10 cm,
(i). Determine the mass to the container.
(ii). What force will be required to depress the bottom of the container to a depth of 10 m in water if the trapped air has constant temperature?
Atmospheric pressure = 100 KPa
