Interpreting Scale from a Picture

Scale is difficult to determine with nothing to refer to. The One World Trade Center building has a cube-shaped base that is 200 ft in height, with trapezoid and triangle faces rising above the cube. You can use the picture of the One World Trade Center, as well as what you know about the height of its cube base, to approximate the height of the building.

  • Approximately how many 200-ft sections is the building in height?
  • How tall do you think the building is?


  • What do you need to measure on the drawing to find the scale of the drawing?
  • To find the height of the building, think about what you need to solve for.
  • How can you set up the equation?
