Unit 3 Lesson 6

Area, Volume, & Density

Complete this Quizizz Lesson, then complete the Lesson 3.6 Practice Problems assigned to you in Canvas.

2

Population Density

We can calculate the population density of a given area by dividing the number of people living there by the "area" of the place (total number of square miles, km, meters, etc.)

Population Density = population/area

In 2018, Augusta had a population of 196,807. Augusta has a land area (not including water areas) of 306.2 square miles. What was the population density in 2018?

people per square mile (round to the nearest whole person).

4

Fill in the Blanks

A circular petri dish has a radius of 3 cm. Sierra counts 95 bacteria in the petri dish when she examines it under a microscope. What is the density of the bacteria per square centimeter? (round to the tenths place, type in number only)

*Hint: the area of a circle is A=πr2A=\pi r^2

5

The amount of molecules in an object. How much mass is in a certain volume will determine its density.

6

Volume & Density

You can find the density of a 3 dimensional object by dividing its mass by its volume.
