Volume is expressed in cubic units of measurement: inches, feet, yards, miles,
milliliters, centimeters, decimeters, meters, kilometers, etc.
Using the funnel, ll the 1-liter graduated cylinder with plastic ll.
Remove the base of the chosen solid and ll it with the plastic ll. Note the
amount of ll required. Repeat two or three times to ensure accuracy.
Repeat the process with all of the shapes.
Have the students evaluate their data by listing the solids in descending order
from most volume to least volume. Compare completed list with original
estimation.
Discuss: What other materials could be used for the measurements?
What relationships exist between the various solids? How does the volume
of the cube compare to the volume of the square pyramid? Explain any other
comparisons derived from the data.
