Olga makes origami ornaments that are rectangular pyramids. She covers the bottom in black foil, one pair of opposite sides in blue foil, and the second pair of opposite sides in gold foil. How much of each colored foil, measured in square centimeters, does Olga need to cover 1 ornament? How much total foil does she need to make 1 ornament? Calculate the amount of foil needed to make 100 ornaments. Use the diagram below for your calculations. Calculate the surface areas of the faces.
