notes: label: Description
content: 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.
label: Description
content: The unpainted wooden model has eight rectangular sides and an octagonal top and bottom. Four straight lines join opposite vertices of the octagons on each end, suggesting how the solid might be divided into eight triangular prisms. A mark on a label on the side reads: OCTAGONAL PRISM. Further text discusses the surface area and volume of the solid.
label: Description
content: In the series of plane figures, Ross compared the area of a circle to the area of circumscribing polygons of increasing numbers of sides. To demonstrate the volume of a cylinder, he compared it to various regular prisms, including the octagonal.
