Question

a single tree produces about 2.6 × 10² lb of oxygen each year. the amazon rainforest has about 3.9×1011 trees. about how many pounds of oxygen are produced in the rainforest each day ? enter your answer in the box. 2.8 × 10 lb

Answer 1

In one year 3.9 x 1011 trees (3942.9) would produced 1,025,154 lbs of oxygen

take 2.6 x 10 to the tenth power = 260
then 3.9 x 1011 = 3942.9
than take 3942.9 x 260
= 1,025,154

hopefully I'm not wrong, hope this helps, good luck.
