Question

According to the United States Department of Agriculture (USDA), Texas had 11,300,000 cows in 2013. If one cow produces about 207 g of methane (CH4) per day, how much methane was produced by the cows in Texas in 2013?

Answer 1

1 cow produces 207 g of CH4 per day

11,300,000 cows produces 207 * 11,300,000 g of CH4 per day

                                                = 2339100000 g of CH4 per day

for 365 days amount of CH4 gas = 365 * 2339100000 g for 2013 year

                                                           = 853771500000 g for 2013 year
