Materials: Modeling clay

Keywords: Triangular, prism, triangular prism, cross-section, three-dimensional

Step 1: Roll the clay into a long, straight, thick roll of equal thickness, like you are making a large snake.

Step 2: Shape or slice off the sides flat to give it three rectangular sides and a triangular cross-section.

Step 3: Shape or slice off the ends flat with a thread or a knife.

Step 4: See below what your triangular prism might look like.

See below the sculpture 'Texas Triangles' by artist Charles Ginnever. How many triangular prisms make up the sculpture?
