How tall are the buildings?

Each floor of a building is approximately 10 feet. The building
in the picture on the far left has 9 floors. We can count by tens
to get 90 feet for the height of this building. Now, let’s
estimate the height of the shortest building. To do this we simply
count 4 floors or 40 feet. Look at the tallest building. Did you
count 14 floors? That would make the tallest building 140 feet.
The last two buildings are about the same height, at 11 floors
each, How tall are the buildings? If you said about 110 feet,
YOU’RE RIGHT!

Here are some photos of actual buildings, use the method from
the example above to estimate how tall they are.
