 TOPICS This page: perimeter, area, volume Perimeter, Area, and Volume The problems in this section explore the numerical and/or physical properties of perimeter, area, and/or volume, which are among the most important (and practical!) topics in a standard geometry curriculum. Some problems deal with classic geometric relations, but many incorporate practical applications. Heron's formula would be an appropriate search topic as a special subject.
