QUESTION 1 (a) A rectangular barge of 11.6 m x 4.2 m x 1.8 m (length x wide x depth) is used to transport sand (density = 1280 kg/m?) through a fresh water lake (density = 1000 kg/m²) as shown in Figure Q1(a). The barge itself made of steel weighed 40,000 kg. Sand IT Depth =1.8 m Water Tevel Length =11.6 m- Figure Q1(a): Rectangular barge floating in seawater (i) Determine the volume of sand carried inside the barge if it is submerged at 1.4 m depth. [7 marks] (ii) Determine the submerged level of an empty barge when it moves to seawater (density = 1025 kg/m3). [5 marks]
