Total Rainfall = rainfall mm x area covered
In order to ensure that our values are correct we will need to convert the area covered (the total area of the two tanks) from metres into millimetres. We will also need to convert the total rainfall (KL) into mm.
Total Rainfall = rainfall mm x 8558.25m
8558.25 = ? mm
8558.25 x 100 = 855825cm
855825 x 10 = 8558250mm
Total Rainfall = rainfall mm x 8558250mm
= rainfall mm x 8558.25
1KL = 1000000000mm
3.51125KL = ? mm
3.51125 x 1000000000 = 3511250000
3511250000 = rainfall mm x 8558.25
3511250000 8558.25 = rainfall mm
410276.6337 = rainfall mm
rainfall mm = ∛(total rainfall)
= ∛410276.6637
= 74.30629279mm
