1. Note: Many problems in this packet will be completed together in class during review time. Students are not expected to complete every single problem in the packet. They should complete the “starred” problems on each page-- in addition to studying the notes and past quizzes– in order to be fully prepared for test. TOPICS COVERED ON “Geometry” TEST: STUDENTS HAVE FORMULA SHEETS AND WILL BE ALLOWED TO USE THE FORMULA SHEET ON THE TEST! Quadrilaterals Transformations on the Coordinate Plane: - Translations (Slides) - Rotations (Turns) - Reflections (Flips) - Dilations (Re-sizing) Volume of both Rectangular Prisms and Cylinders Surface Area of both Rectangular Prisms and Cylinders Changing Attributes (length, width, height) Be able to: -Know and understand (for transformations): “Right or left changes ________________! Up or down changes ________________! -Describe in your own words the difference between Volume and Surface Area. -Look at a “net” (flat version of 3-D figure) and explain how the net relates to Surface Area of the figure.

11. Answer the following questions : 1)A rectangular prism has a volume of 24 cm³. If the height of the prism triples, and the other two dimensions stay the same, what is the new volume? 2)One planter box holds 36 in.³ of dirt. A smaller planter box holds 12 in.³ of sand. If the length and width of both planter boxes are equal, and the height of the larger planter box is 6 ft., then what is the height of the smaller planter box? 3)Andrea’s jewelry box is 8 in. long, 3 in. wide, and 4 in. tall. She gets another jewelry box that is the same size, except that it is 6 in. wide. Compare the volume of the original jewelry box to the volume of the larger jewelry box (be specific). 4)One fish aquarium measures 16 inches long, 5 inches wide, and 10 inches in depth. If another aquarium is the same size– except its length is 8 inches long, what is the volume of the smaller fish aquarium? 5)One rectangular prism has a volume of 8 in.³ Another rectangular prism has a volume of 40 in.³ The length and width of both prisms are the same. If the height of the smaller prism is 2 in., then what is the height of the larger prism? 6)If the volume of one rectangular prism is twice the volume of another prism, what could be the length, width, and height of both the smaller and larger rectangular prisms?
