We began a new unit on volume and area of solid objects today. This is our first study that includes 3-dimensional figures. We went through the area and volume calculations associated with prisms today. New terms that were introduced were lateral faces, lateral edges, lateral area, and total area. We continue to use the area formulas that we learned in a previous chapter.
Assignment: section 12-1; page 478 ; WE 1-14 all, 20, 21
