Volume and Density Summary

Play an AI-generated podcast conversation about this lesson

What does volume measure?

The density of an object

The amount of water an object can hold

The mass of an object

The space an object takes up (correct)

What is the equation used to find density?

$density = mass / volume$ (correct)

$mass = volume / density$

$density = volume / mass$

$mass = density / volume$

When does an object have a high density?

When it is heavy and compact (correct)

When it is hollow and can hold a lot of water

When it changes color, texture, or shape

When it is light and takes up a lot of space
