The question provides criteria in two different situations, and it is required to find the weight of construction materials and equipments in Barge.
The problem is approached through Archimedes principle which states that weight of water displaced equals weight of material immersed. The first criteria is used to calculate the weight of barge in fresh water. Second criteria is used to calculate total weight in seawater. The difference of two value is calculated to determine the weight of materials and equipments.
