    Ross, W. W.

    Description

    This is one of 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 the frustum of a triangular pyramid has three trapezoidal sides and a triangular top and base. It is dissected into three pieces. A paper label attached to one side reads: Triangular Frustum.
