Question (1) A cubic Aluminum container (RD = 2.7) has a side length of 1 m and thickness of 1 cm and is floating inside a water tank. The container is empty and open from the top (i.e.: has only 4 sides and one base). Assuming the density of water is 1000 kg/m", determine: A. Height of the container floating above water. B. Volume of water we can pour into the container before it sinks. If the empty container is...
