Vocabulary:

Example:

Let’s say we have a box….

To find the volume, we need to figure out how many cubes would
fit inside the box without any gaps or overlaps.

We would fill up the box with as many cubes as we can without
any gaps or overlaps! The number of cubes would tell us the
VOLUME!

Let’s try it:

Count the
number of
cubes
inside each
box.
