GED® Geometry: Volume & Surface Area Mastery

A deep GED® Geometry course on three-dimensional solids. Students learn what volume and surface area mean, then master the formulas for boxes, cubes, cylinders, cones, and spheres, plus surface area from nets. The course stresses the big idea that prism volume is base area times height, tells volume apart from surface area, and applies both to real-world filling, capacity, and wrapping problems. Every solid has a labeled diagram, every lesson has an interactive self-check, and every practice answer explains the method and adds a Pro tip. The GED® provides a formula sheet, so the focus is on choosing and using the right formula.
