12/01/2009 Area and Volume Definitions: Area – the amount of space inside a two- dimensional shape. Surface area – the total area of all surfaces on a three-dimensional object. Volume – the amount of space a three- dimensional object occupies. Area is measured in "square" units. The area of a figure is the number of squares required to cover it completely. Volume is measured in "cubic" units. The volume of a figure is the number of cubes required to fill it completely © 2013 International Technology and Engineering Educators Association, STEMCenter for Teaching and Learning™ Foundations of Technology © International Technology Education Assoc
