(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A violent rainstorm dumps 1.7 cm of rain on a city 4.0 km wide and 7.0 km long in a 2.0 hr period. How many metric tons of water fell on the city?

2. Relevant equations

1 ton = 10^3 kg

1 cm^3 of water has a mass of 1 g = 10^-3 kg.

Density of water is 1.0 g/cm^3

3. The attempt at a solution

Knowing that density of water is 1.0 g/cm^3...

I first calculated the volume, which is v = (1.7 cm) (4000 cm) (7000 cm) = 4.76E7 cm^3. To get the mass in metric tons, I did the following: mass = (4.76E7 cm^3) (1 g/cm^3) (1 kg / 1 000 g) (1 metric ton / 1000 kg) = 47.6 metric tons.

When I entered it into the computer, it said it was incorrect. Please help!
