Flooding Danger
1. During a summer storm, 1 cm of precipitation that used to soak into the ground now falls on a house roof measuring 18x12-m, and from there down the gutters and into a drain. How much water in cubic meters (m^3) goes down the drain?
2. What if it rains to a depth of 1cm on 20 homes (18x12-m roofs), how much goes down the drain in m^3 and gallons?
3. What is the volume of 1-cm rainfall over an area of 401 km^2. What is it in m^3?
4. If urbanization brings precipitation to 90% vs 20% in undeveloped land, how much water goes into the ground, in m^3? (1-cm rainfall over an area of 401 km^2)
5. How can you solve this issue?

I'll get you started, but that is all. get all you units the same. Convert the rain fall into meters and multiply it by the size of the roof to get the volume of rain on that area. keep multiplying that by the number of homes to get the total for the neighborhood. Hope that helps.

I agree with Doc E.
The solution is very straightforward math, just get all your units the same. You already have metric, so its easy.
Hint # 1: 1 cubic meter = 1000 liters = 1 tonne of water
Hint # 2: 100 cm = 1 m.
Just follow it step by step, just multiply it out, nothing difficult here...doing your own homework will teach you how to solve your own problems.
