To estimate the 'as discarded' density of 1000 kg of typical residential waste based on the given data, the process involves calculating the individual mass of each waste component and then determining the overall volume of the waste mixture. The density of each component needs to be known or assumed based on typical values. ### Step 1: Calculate the Mass of Each Component The mass of each component is calculated by multiplying the percentage of each material by the total mass of the waste, which is 1000 kg in this case. * Food Waste: 15% of 1000 kg = 0.15 * 1000 = 150 kg * Paper: 45% of 1000 kg = 0.45 * 1000 = 450 kg * Cardboard: 15%
