2. CALCULATING AREA AND VOLUME AREA = (bh÷2) VOLUME = (bh÷2)·H÷3
Using the following formulas, find the area of the small and large triangle, as well as the volume of the small and large tetrahedron. (REMEMBER UNITS!!
AREA = (bh÷2) VOLUME = (bh÷2)·H÷3
(One Cell) b = base: ____” (Total Assembled Kite) b = base: ____”
(One Cell) h = height: ____” (Total Assembled Kite) h = height: ____”
(One Cell) H = 3-D height: ____” (Total Assembled Kite) H = 3-D height: ____”

3. Tetrahedral Kite Open Response Questions
1. What is the purpose of the bridle? Would it work in another location on the kite? Why or why not?
2. What is Newton’s Second Law? How does it apply to the flight of your kite?
3. On the tetrahedral kite pictured on the open response answer sheet, label the following: a vertex, a face, a polygon, a tetrahedron and then draw a bridle on it.
