Question

The Sears Tower in Chicago is 1454 ft tall. Calculate its height in meters.
Express your answer using four significant figures.

Answer 1

To convert the height of the Sears Tower from feet to meters, we can use the conversion factor where 1 foot is equal to 0.3048 meters.

The calculation is as follows:

\[
\text{Height in meters} = \text{Height in feet} \times \text{conversion factor}
\]

\[
\text{Height in meters} = 1454 \, \text{ft} \times 0.3048 \, \text{m/ft}
\]

Now performing the calculation:

\[
\text{Height in meters} = 1454 \times 0.3048 = 443.15072 \, \text{m}
\]

Rounding this result to four significant figures:

\[
\text{Height in meters} \approx 443.2 \, \text{m}
\]

Thus, the height of the Sears Tower in meters is **443.2 m**.
