6.6mm of rain fall onto a rectangular roof 8m long and 6m wide.
The rain water drains into a cylindrical barrel of diameter of 60cm.
How far does the water level rise in the barrel?
~~~~~~~~~~~~~~~~~~~~~~~~~~
To find the water level rise in the barrel, take the volume of the rain
volume of the rain = 0.66 cm * 800 cm * 600 cm = 316800 cm^3
and divide it by the area of the barrel base/(bottom)
area of the barrel base/(bottom) = = = 2827.433 cm^2.
You will get the water level rise of = 112 cm (rounded).
Remember, that in such calculations, you should use the dimensions in consistent units.
