Volume is expressed in cubic units of measurement: inches, feet, yards, miles, milliliters, centimeters, decimeters, meters, kilometers, etc.

Using the funnel, fill the 1-liter graduated cylinder with plastic fill. Remove the base of the chosen solid and fill it with the plastic fill. Note the amount of fill 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.

Characteristics of Geometric Solids

Work with the students to create a chart like the one below to record their own observations:
