800 jerrycans fill a tank. One jerrycan weighs 20 kg. How many litres does the tank hold? A bucket contains 45.6 litres of water. The empty bucket weighs 3 kg. (i) What is the mass of the full bucket?

Morning Placide — let's get this done. Here are the solutions for problems 2 and 3. Problem 2: "800 jerrycans fill a tank. One jerrycan weighs 20 kg. How many litres does the tank hold?" Assumption: We assume that "One jerrycan weighs 20 kg" refers to the mass of the water contained in one jerrycan. We also use the density of water, where 1 kg of water has a volume of 1 litre. Step 1: Determine the volume of water in one jerrycan. Given that 1 kg of water is approximately 1 litre, if one jerrycan contains 20 kg of water, then its volume is 20 litres. Volume per jerrycan = 20 kg × 1 L1 kg = 20 L Step 2: Calculate the total volume the tank holds. The tank is filled by 800 jerrycans. Total volume = Number of jerrycans × Volume per jerrycan Total volume = 800 × 20 L Total volume = 16000 L The tank holds 16000 litres. Problem 3: "A bucket contains 45.6 litres of water. The empty bucket weighs 3 kg." "(i) What is the mass of the full bucket?" "(ii) What is the volume of the water that fills the bucket in cm³?" (i) Mass of the full bucket Step 1: Calculate the mass of the water. We use the density of water, where 1 litre of water has a mass of 1 kg. Mass of water = 45.6 L × 1 kg1 L = 45.6 kg Step 2: Calculate the total mass of the full bucket. Mass of full bucket = Mass of empty bucket + Mass of water Mass of full bucket = 3 kg + 45.6 kg Mass of full bucket = 48.6 kg The mass of the full bucket is 48.6 kg. (ii) Volume of the water that fills the bucket in cm³ Step 1: Convert the volume from litres to cubic centimetres. We know that 1 litre is equal to 1000 cubic centimetres (1 L = 1000 cm^3). Volume in cm^3 = 45.6 L × 1000 cm^31 L Volume in cm^3 = 45600 cm^3 The volume of the water that fills the bucket is 45600 cm^3. Drop the next question.
