Question
A heavy rainstorm dumps 1.0 cm of rain on a city 8 km wide and 9 km long in a 2 hour period.
How many metric tons (1 metric ton = 10^3 kg) of water fell on the city? (1 cm^3 of water has a mass of 1g = 10^-3 kg)
What I have thus far:
72 km^2 x (1E^10 cm^2/1km^2) x (10^-3 kg/ cm^3) x (1 metric ton/ 10^3 kg)

you forgot the depth: 1cm
Though it makes the units come out, it does not affect the final numerical value.
Looks good.
