Ross Solid, Square Prism Inside a Cylinder
date: label: date made
content: ca 1895
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. It consists of a hollow metal cylinder with a bottom circle and a hollow metal square prism with bottom square. The prism fits inside the cylinder. An incomplete paper label on the cylinder reads: Oblong or Square P [. . .] (/) [. . .]: - Area of Base x Alti [. . .].
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 inscribed in it. Compare models 1985.0112.208 and 2012.0112.209.
