For this activity, your task is to collect two 3-D items from your environment in order to calculate their volumes and surface areas. One item will be either a prism or a pyramid, the other item will be either a cone or a cylinder. Some items that will work for this activity are canned goods, food storage containers, recyclable cardboard items, etc.

Make sure to show all work for your calculations and answer each reflection question in two to three sentences.
