I'm working on a math assignment...

My teacher wants me to find rainfall data and then work out the volume of water that would fall on a roof. I've already worked out the roof area but the roof is made up of multiple squares.

The teacher would like me to detail how I'm going to do this, then do it and then display my data in a graph and table.

I vaugely (but not totally) understand how to work out the rainfall volume in m3 but I don't know how to use the data I've collected to do this (I have collected 13months worth to make it more reliable)

Could somebody step me through what I need to do and explain how to align my 13months of data with my task. Also how to tie in the graph and table?

Thanks soooo much

Volume of rainfall is the area it falls on, times the "height" of the fall. Rainfall x area gives volume.

Graphs? Graphs tell a story, what do you want to tell?
