Abstract

1278544 Teaching metric dimensions H GRUBB 25 May 1971 [15 July 1970] 34382/70 Heading G5G An educational device for teaching metric dimensions comprises a cube or sphere formed of a material having a specific gravity of one, and having a volume of one cubic centimetre. Further cubes or spheres of specific gravity of one may be provided, the edge dimensions or radii being integral multiples of the edge dimension or radius of the basic cube or sphere, so as to form a series progressively increasing in volume and weight. Supplementary sections 9 may be provided to increase the size of a block 8 to that of the next in the series. The material is a plastics, such as polypropylene or an epoxy resin, blended with a filler, such as mica, talc, spheroidal phenolic microballoons, exfoliated lamina vermiculite, or hollow glass spheres.
