Again, this is a conversion question. You could use the information from parts A and B, or just figure it out with units directly. I'll look at the one-story house I used to live in. Plus the two little piano windows about 2 sq. There was a total of 100 sq.
Modern houses have a lot more windows.
Your estimate may be very different from mine. This question is really asking to check the dimensions. We need a meters on top, and then a seconds on bottom. We have seconds cubed on top. We can get the area of the city, and so we can get the volume of rain that fell on the city.
