A single tree produces about 2.6 × 10^2 lb of oxygen each year. The Amazon rainforest has about 3.9 × 10^11 trees. About
how many pounds of oxygen are produced in the rainforest each day ? 2.8 × 10^? lb




Sagot :

(2.6 * 10^2)/365 = 260/365
(260/365) * (3.9 * 10^11) = 2.778 * 10^12 (3.d.p.) or 2.8 * 10^12 (1.d.p.)
