Hey I'm working on a math assignment and I'm trying to work out the total amount of rainfall that fell in a certain area. Would this formula be correct?

Total rainfall = rainfall mm x duration of storm minutes x area covered

And with my rainfall mm I change it out so instead of 1mm cubed it is 1mm x1mm x 1mm?

Thanks!

Also, sorry, if I already HAVE the total rainfall and I'm solving for the rainfall mm but I don't need the duration of the storm would this formula be ok?

Total rainfall = rainfall mm x area covered

Your "total rainfall" will represent the volume of water that fell in the particular area covered. If the final answer is to be in cubic metres, then the rainfall in mm has to be divided by 1000 to convert it to metres.

Thanks! Ermm what if I have the 'total rainfall' in KL?

A KL is a kilo-litre, or 1000 litres, which is the same capacity as m³.

To calculate the total amount of rainfall in a certain area, you need to consider the rainfall rate (in mm/hour) rather than the volume of rainfall (in mm^3). Here's the correct formula:

Total rainfall = rainfall rate (mm/hour) x duration of storm (hours) x area covered

Make sure you are consistent with the units when performing calculations.

To convert the rainfall mm to rainfall rate, you need to know the duration of the storm in hours. Let's say you have the rainfall volume in mm and want to convert it to mm/hour:

1. Determine the duration of the storm in hours. For example, if it rained for 60 minutes, the duration would be 1 hour.

2. Divide the rainfall volume (in mm) by the duration of the storm in hours. For example, if you have 10 mm of rainfall over 1 hour, the rainfall rate would be 10 mm/hour.

Then, you can use the revised formula to find the total rainfall:

Total rainfall = rainfall rate (mm/hour) x duration of storm (hours) x area covered

Remember to ensure that the units are consistent throughout the calculation.
