    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
