- DEA agents watch drug smugglers load cocaine onto a fishing boat in a Mexican river to transport it down the river to the ocean, and then to Miami. To estimate how much cocaine was loaded, they measure how much further the boat sinks into the water after being loaded. If the boat’s area at the waterline is 50 m2 and it sinks by 2 cm, how much cocaine was loaded?The material that holds the world record for being the least dense solid is silica aerogel, with a density of only 1 mg/cm3. What would be the mass of a cube of silica aerogel that measured 1 m on each side? Can you show me step by step how to do this? I know that Density=mass*volumeWhich of the following statements accurately defines density? Density is the force exerted on an object due to gravity. Density is the amount of matter in an object. Density is the mass of an object per unit volume. Density is the volume of an object divided by its weight.
