Interpret Scale Drawings

In this drawing of an amoeba, the scale is in µm, which stands for micrometer; 1 micrometer is 11,000,000 of a meter.

  • What is the approximate length of the amoeba in micrometers?
  • About how long is the nucleus in micrometers?

Challenge Problem

The Burj Khalifa in Dubai is currently the tallest building in the world at 2,717 feet—which is a little more than half of a mile.

  • If a model of the building were made at a scale of 50 : 1—that is, 50 ft to 1 in.—how tall would the model be?
