Volume, Density, and Population Density

Front

What is the formula for calculating the volume of a rectangular prism?

Back

Volume = length × width × height

Front

Define density in terms of mass and volume.

Back

Density = mass/volume

Front

How do you calculate the density of an object?

Back

Density = mass of the object / volume of the object

Front

What is the formula for the volume of a cylinder?

Back

Volume = π × radius² × height

Front

If an object has a mass of 200g and a volume of 50cm³, what is its density?

Back

Density = 200g / 50cm³ = 4 g/cm³

Front

What is the unit of density in the metric system?

Back

g/cm³ (grams per cubic centimeter) or kg/m³ (kilograms per cubic meter)

Front

How do you find the height of a cylinder if you know the volume and radius?

Back

Height = Volume / (π × radius²)

Front

What is the population density formula?

Back

Population Density = Total Population / Land Area

Front

If a state has a population of 10,000 and an area of 500 square miles, what is its population density?

Back

Population Density = 10,000 / 500 = 20 people per square mile

Front

What is the volume of 1 liter of water in cubic centimeters?

Back

1 liter = 1000 cm³
