1. The problem statement, all variables and given/known data
A cubic centimeter in a typical cumulus cloud contains 50 to 500 water drops, which have a typical radius of 10 µm. For that range, give the lower value and the higher value, respectively, for the following.
(a) How many cubic meters of water are in a cylindrical cumulus cloud of height 2.7 km and radius 1.0 km?
give the lower and upper limit

2. Relevant equations

3. The attempt at a solution

i have converted the units to m cube because thats what the answer wants but i just don't know how to continue

You need to work out the volume of a sphere 10um in diameter - this and the 50-500 gives you the volume of water in 1 cc
Then you need to know how many cubic cm there are in a cubic metre.

The volume of the cloud is the area of circle of radius 1.0km times the height 2.7km, work this out in cubic metres.

so do i multiply the volume of the sphere with 50 and 500 separately

Yes you would because it says to give the upper and lower limit.
