1. METALS Toni found an irregular piece of metal. She dropped it into a container partially filled with water and measured that the water level rose 4.8 centimeters. The square base of the container is 8 centimeters on a side. Toni measures the mass of the metal to be 450 grams. What is the density of the metal? Round to the nearest tenth. 2. POPULATION DENSITY The population of Colorado in 2009 was about 5.024.748. Tlhe land area can be approximated by a rectangle with coordinates (0. 0). (369, 0). (369, 281), and (0, 281), with each unit on the coordinate plane being I mile. What was the population density of Colorado in 2009? 3. POPULATION DENSITY In 2000, Texas had about 2.74 persons per household, 7,393,354 households, and a land area of about 261,797 square miles. What was the population density of Texas in 2000?
