3.4 Unit Three Quiz Below are the steps and questions to this portfolio broken down: Step 1 Contest Directions - These are only the directions, you can ignore this step. Step 2 The Challenges - Challenge #1 – The Penny Problem - Find the volume of a penny with the given dimensions. - Find the volume of the glass jar with the given dimensions. - With these volumes, use division to find how many pennies would fit in the glass jar. - Challenge #2 – Tennis Trouble - Find the volume of a tennis ball with the given dimensions. - Find the volume of the cylinder, volume of the cone, and add the two volumes together. - Use division with the volume of the tennis ball and the combined volume of the cylinder and cone to find how many tennis balls fit into the cylinder and cone. - You do not have to find how many tennis balls would fit if the dimensions are doubled, you can skip that part of this challenge. - Challenge #3 – Giant Gum - Find the volume of the pyramid gum with the given directions. - Find the volume of the sphere with the given directions. - Using division, find how many pyramids will fit inside the sphere. Step 3 Answering the Questions - 1) Find the volume of the total number of tennis balls that fit in the cylinder and subtract that volume from the volume of the cylinder to find the empty space. I want you to answer the second part of the question on your own. - 2) Look at lesson 2 to find where the volume of a cylinder is derived from. - 3) Choose either a cone or a pyramid and tell from which formula its volume is derived from. - 4) Look at lesson 2 to find the answer for this question. - 5) For this question, it is completely your opinion. I just want you to explain why you choose your shape. For your proof, try looking at the volumes of different figures with similar dimensions.
