ok so what you want to do is multiply the amount a tree produces in a year by the number of trees in the rainforest and then divide by 365. That should be your solution

2.6x10^2=260
3.9x10^11=390000000000
260x390000000000=101400000000000
101400000000000/365=277808219178.0822
so 277808219178.0822 is my answer
