Area and Volume

Description

What are the geometric principles behind the sinking of the Titanic-and how is a ship of its size able to float in the first place? This program examines applications of area and volume, using the Titanic, the Louvre's Glass Pyramid, and New York's CitiGroup Building to illustrate the concepts of volume and density, surface area, and surface area-to-volume ratio. Knowing the proportion of the Citigroup's surface to its interior space is the first step in determining how the building can be kept cool in summer and warm in winter. Its unusual shape-a combination of a square and a triangular prism, with a 45-degree-angled roof and stilt-like base-adds complexity to the calculation.
