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 of volume, so simply divide the mass of the candle by its volume: = 0.46 ounces/cubic inch. 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 density than the rest of the candle. In this task, you will apply this knowledge of density to answer some questions about the following scenario. Harold is a woodworker and is interested in finding the density of two different types of wood. He bought a pine log that has a 5-inch radius and is 30 inches long. The weight of the log is approximately 42.63 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 8.05 pounds. B. What is the density of the pine log? Show your work

Ответ:
396cm
Step-by-step explanation:
55 x 40 = 2,200
2,200 x 180 = 396,000
396,000 / 1000 = 396
396cm
