Mathematical Model – Cube and Octahedron, Inscribed
Accession Number: 2016.mat.23
Mathematical Model – Compound of 5 Octahedra
An assembly of transparent yellow, purple, and green coloured plastic sticks joined at their ends by rubber bands. The description in the Department of Mathematics display reads as follows:
“By moving the vertices of the octahedron towards the centre of the model one gets the octahedron inscribed in the cube, by moving them out one gets the cube inscribed in the octahedron.”
Primary Materials: Plastic, rubber
Dimensions (cm): Longest dimension = 25 cm
Function: Pedagogical mathematical model.
Good/ Fair: The rubber bands that bind this model together are deteriorating. Some have come apart completely.
Date of Manufacture: c. 1960
Donated to UTSIC: No
