You look up at the cloudy sky and see some spherical cumulus clouds. How do you measure the volume of water it holds? Scientists use advanced techniques to do it. But we can roughly calculate it using a bit of Math, if we know the density of the cloud. Different clouds have different densities depending on how much water they can hold. Cumulus clouds might have a density of around 0.3 grams/cubic metre. The volume is calculated using the formula for the volume of a sphere V = (4/3)*Pi*Radius cubed!
What if it is a conical cloud? Have a look at the video…
Similarly, once we know their volumes, we can estimate their masses too, using the formula Mass = Density x Volume. So that’s a bit of Math for you to think about as you walk under the clouds!
