It's one of the most recognizable residences in the world, but just how big is the White House? Even if you've never visited, this lesson will give you a sense of its scale.
Students use a 1:480 scale model of the White House to find the surface area of the walls and how much it would cost to paint them. They figure out how many models it would take to fill up the building, and finally, how much it costs to heat in the winter. In the process, they confront misconceptions about how area and volume change as distance changes.
