1. To calculate the density of people per block in the neighborhood, divide the total number of people (1,620) by the number of residential blocks (18). The density of people per block in the neighborhood is 90 people per block. This means that on average, there are 90 people living in each residential block in the neighborhood.
2. To determine which location is more densely populated, calculate the population density of Hawaii by dividing the population by the area (1,440,196 people / 10,931 sq mi = 131.75 people per square mile). Compare this to the population density of the village in France (10.19 people per square mile). Hawaii is more densely populated than the village in France, with a population density of 131.75 people per square mile.
3. To determine if the ice block will float or sink in water, calculate its volume by multiplying the height, length, and width (2 cm x 2 cm x 5 cm = 20 cm3). Since the density of water is 1 g/cm3 and the mass of the ice block is 18.4 g, divide the mass by the volume to find its density (18.4 g / 20 cm3 = 0.92 g/cm3). Since the density of the ice block (0.92 g/cm3) is less than the density of water (1 g/cm3), it will float in water.
1. There are 1,620 people who live in a neighborhood. If the neighborhood contains 18 residential blocks, calculate the density of people per block in the neighborhood. In 1–2 sentences, explain how you determined the density
2. The area of the state of Hawaii is 10,931 square miles, and its population is 1,440,196 people. The population density of a village in France is 10.19 people per square mile. Which location is more densely populated? In 1–2 sentences, explain how you determined your answer.
3. The density of water is approximately 1 g/cm3
. An ice block with a height of 2 cm, length of 2 cm, width of 5 cm, and mass of 18.4 g is dropped in water. Will it float or sink? In 3–5 sentences, show your calculations and explain how you arrived at your conclusion
