Cone Dissected into Two Pieces, Ross Solid #12

Description
This is the twelfth in a series of models illustrating the volume of solids designed by William Wallace Ross, a school superintendent and mathematics teacher in Fremont, Ohio.
The unpainted wooden model of a cone is divided into two pieces by a plane parallel to the base. A label on the side of the frustum reads: CONE. Ross compared the volume of a cone to the volume of a pyramid with a regular polygon for its base.
