Unit 7 Test Review (OL) :: Volume & Density

Front

What is the formula for calculating the density of an object?

Back

Density = Mass / Volume

Front

How do you calculate the volume of a rectangular prism?

Back

Volume = Length × Width × Height

Front

What is Cavalieri's Principle?

Back

Cavalieri's Principle states that if two solids have the same height and the same cross-sectional area at every level, they have the same volume.

Front

If a city has a population of 8792 people and an area of 6.5 square miles, how do you find the population density?

Back

Population Density = Population / Area = 8792 / 6.5 = 1353 pop/mi²

Front

What is the volume of a composite figure?

Back

The volume of a composite figure can be found by calculating the volume of each individual shape and then summing them up.

Front

Which measurement is NOT needed to calculate the volume of a prism?

Back

The measurement that is NOT needed is the one that does not contribute to the volume calculation, such as the width if it is not part of the base area.

Front

What is the unit of measurement for density?

Back

Common units for density include g/cm³, kg/m³, and g/mL.

Front

How do you find the volume of a cylinder?

Back

Volume = π × radius² × height.

Front

What is the relationship between mass, volume, and density?

Back

Density is a measure of how much mass is contained in a given volume.

Front

If a rock has a mass of 14g and a volume of 2cm³, what is its density?

Back

Density = Mass / Volume = 14g / 2cm³ = 7 g/cm³.
