Summary

This equal volume solids set is used to explain why bubbles are round. Spherical, to be exact. The sphere is the shape that uses the smallest surface area to enclose the largest volume! The set includes five solids: sphere, cube, pyramid, cylinder, and torus. Each has a volume of 125 cm3, and the surface areas range from 121 cm2 (sphere) to 168 cm2 (pyramid).

There are two Projects recommended with this set. One is to challenge students to make a bubble in another shape, using a frame or other method. Another is to challenge students to design another shape with the same volume as the set, using their knowledge of geometry and the 3D design program of their choice, and then to find its surface area.
