Task 1 finding density all objects have mass. mass is the amount of material in an object, usually measured by its weight. earlier in this unit, you studied the volume of objects. when you combine these two concepts, you get a useful measurement called density. the density of an object is its mass per unit of volume. imagine two objects in which the larger one actually weighs less than the smaller one. this difference in weight is attributed to density. consider a candle that has a volume of 96 cubic inches and a weight of 44.16 ounces. what is the density of the candle? the density is defined as its mass per unit volume, so simply divide the mass of the candle by its volume: . in this case, you are finding the average density of the candle. in most cases, you will be finding the average density of objects because most objects do not have a uniform density. for instance, the portion of the candle where the wick is might have a different d
