Convert the following correct to two decimal places: a 278 kg to pounds, rounded off to the nearest pound. b The weight of a large tuna fish of 980 lb to kilograms. c \( 2,5 \mathrm{oz} \) of sugar in a recipe to grams. d 1 pound expressed in ounces. e \( \quad 42 \mathrm{oz} \) of flour in a recipe to kilograms. f 50 g expressed in kilograms. Cindy's mass is 58 kg . Convert her mass to pounds. In a recipe book, a ratio of \( 125 \mathrm{~g}=4 \mathrm{oz} \), or \( 300 \mathrm{~g}=10 \mathrm{oz} \) is given. a Convert 24 ounces to grams, correct to one decimal place: i using both of the recipe conversion factors ii using the actual conversion factor given in Figure 1.4. b What is the range in answers in 3.a.i. and 3.a.ii.? c The recipe book states that its conversions are 'approximate'. Do you think the approximations made in the recipe book are acceptable? Give a reason for your answer. On the morning of the June 23,2000 , the MV Treasure - a bulk ore carrier sank off the west coast of South Africa, causing a major oil spill. The MV Treasure had 1344 metric tonne of heavy fuel oil on board, as well as 56 metric tonne of marine diesel and 64 metric tonne of lubrication oil. All of this fuel except for 205 metric tonne of the heavy fuel oil ended up in the ocean, in the area between Robben Island (near Cape Town) and Dassen Island (off the coast of the West Coast National Park). a How many tonne of fuel spilt into the ocean during this disaster? b If one metric tonne is 1000 litres, convert the answer in 4 . a to litres. c Convert the answer in \( 4 . \mathrm{b} \) to cubic metres. ( 1 litre \( =1000 \mathrm{~cm}^{3} \) ) d If this volume of fuel was to be poured into a rectangular prism with the base having the same dimensions as a soccer field, calculate the height
