200 000 fish at a weight of 150 g each is placed in the tank at the start of day 1. Each day, the fish grows by a percentage of its own body weight. Unfortunately, some fish is also lost due to diseases and similar.
If we have a tank with a radii of 12 meters and a height of 8 meters. How many days can we keep the fish in the tank before the density becomes more than 75 kg/m3, and we need to re-distribute the fish?
Note: we allow some slack in the answer (+- a couple of days)
Good luck! Submit your answer (number of days) to firstname.lastname@example.org!
