Area and Volume in 3D -- Can't Have One Without the Other!
PROFESSIONAL COMMENTARY

Every three-dimensional solid has both a volume and a surface area. Students explore the relationships between volume and surface area by constructing different solids from a given number of cubes. These solids all have the same volume but different surface areas. Extensions of the problem and a complete discussion of the underlying mathematical ideas are included. This mathematically rich problem was originally developed for the Project Discovery Mathematics by Inquiry institutes for middle grades teachers taught in 1992 - 1994 at Ohio State University. Project Discovery was co-funded by the Ohio Board of Regents and the Statewide Systemic Initiative (SSI) program of the National Science Foundation. (author/sw)
