If you say 9x4x3mm for an ant's volume (wild guesstimate based off carpenter ants) (which is way off for most species since they range in size from 0.75 to 52mm[1]) and an Olympic swimming pool as 50x25x2m[2], you get the pool as 2500000000000mm^2 and the ant as 108mm^2 giving an approximate count of 23150000000 or twenty three billion, one hundred and fifty million ants. Which means you'd need about 863931 pools to hold them all at that carpenter size - round up and call it 1.25M pools to hold all the world's population?
