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:

Euler’s Formula  
Euler’s Formula is named after Swiss mathematician Leonard Euler. In the mid-eighteenth  
century, Euler discovered that for any polyhedron, F + V = E + 2. In the formula, F represents  
the number of faces, V represents the number of vertex points, and E represents the number of  
edges. For example, a cube has 6 faces, 8 vertex points, and 12 edges.  
F + V = E + 2  
6 + 8 = 12 + 2  
Have the students use their data from the preceding chart to discover Euler’s Formula. Euler’s  
Formula is true for the first nine solids listed in the table.  
Intervention Strategies  
Scaffolded Instruction: Before providing formulas to students, instead provide the  
definitions of perimeter and area, and opportunities to solve problems that allow students  
to gain data leading to the use of a formula. Begin with two-dimensional shapes before  
advancing to three-dimensional solids.  
Directed Orientation: Use different household items that resemble a cube, cone, sphere,  
cylinder, pyramid, or prism. Have students sort the items by different attributes you provide.  
Then, introduce the formal shapes and have students match the shapes to the corresponding  
household items.  
Free Exploration: Have students fill the solids with rice or water to explore properties of  
volume. Encourage students to make estimations and compare which shapes are able to hold  
more or less than the others.
