Problem 5
Select a different problem
Example:
Convert: 539 square centimeters to square inches.
Solution: First note the equality 2.54 cm = 1 in.
Then divide both sides of the equality by 2.54 cm to maintain the equality.
This gives you
If you next multiply 539 cm
2 by
twice, (this is the same as multiplying by one)
you will cancel cm
2 out and convert your units to in
2 which is your goal.
Or :
(\frac{1in}{2.54cm}) = 83.545in^2 )
(multiply by 1 twice)
To solve this using the graphing calculator below, enter 539(1/2.54)(1/2.54) into the box
to the right of Function f(x)=. Then click on the Plot Graph button.
Your answer will appear below the box as f(x)=83.545...
