Write out the unit multiplier conversion of 7,000 square inches to square
kilometers s using 6 unit multipliers.
-------------------
7000(inches)(inches)(1 cm/0.39 in)(1cm/0.39 in)(1 meter/100 cm)(1 meter/100 cm)
(1 km/1000 meters)(1 km/1000 meters)
= [7000*1*1*1*1*!*!]/[0.39*0.39*100*100*1000*1000] km^2
= [7000/1521000000] km^2 = 0.000004602235371 km^2
