_' TaSk 1 Print 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. Iil'il'hen you combine these two concepisr Iyou 1get a useful measurement called density. The density of an object is its mass per unit ofvolume. Imagine two objects in which the larger one actually weighs less than the smaller one. This differenoe in weight is attributed to density. Consider a candle that has a volume of 95 cubic inches and a weight of 44.16 ounces. What is the density of the candle? The density is dened as its mass per unit volume, so simply divide the mass of the candle by its volume: density = 73% = 0.4.6 utmost/cubic inch. in this caser you are fin ding d1e average density of the candle. In most cases, you will be nding die average density of object-. because most objects do not have a uniform density. For instance, the portion of the candle where the wick is might have a different density than the rest of the candle. Now that you know about density, let's work on some applications. Harold is a woodworker and is interested in nding the density oftwo different types ofwood. He bought a pine log that has a 5-inch radius and is 30 inches long. The weight of die log is approximately 42.53 pounds. He also has an oak board that is 5.5 inches wide, 1.5 inches thick and 3 feet long. The board weighs approximately 8.95 pounds.
