YOUR ASSIGNMENT: Solid Art
Your selections
You meet an artist who makes sculptures out of Platonic solids. Being an excellent
geometer who knows how to use nets to create solid figures, you are intrigued and
want to make your own models.
1. Which combined solid did you select? (Circle one.) (1 point)
Left: Icosahedron with tetrahedrons
Right: Octahedron with tetrahedrons
Construct the models
Nets are two-dimensional patterns that fold into 3-dimensional shapes, so they are a
great tool for analyzing and constructing solids. Use the tetrahedron, octahedron and
the icosahedron tools to help you examine each shape more closely, and to practice
folding each net into a solid.
2. Using the link on the activity page, cut out each net. Fold and tape each net into a
three-dimensional solid. Your solids do not need to be perfect. (9 points: 3 points for

3. Identify each solid. Hint: count the number of faces you can see. (6 points: 1 point
for each blank)
Solid 1: number of faces:_____ name of solid: _____
Solid 2: number of faces:_____ name of solid: _____
Solid 3: number of faces:_____ name of solid: _____
Your solid
4. Look at the polyhedron that you chose at the beginning. Which two solids do you
need to create your polyhedron? How many of each solid do you need?
Answer for your polyhedron. Hint: Each tetrahedron will cover one face of the other
solid. (4 points: 1 point for each blank)
Polyhedron 1: Solid:_____ Number: _____ Solid:_____ Number: _____
Polyhedron 2: Solid:_____ Number: _____ Solid:_____ Number: _____
