Area of Oklahoma = 69,903  Miles squared
                 = (5280 X 5280) X 69,903                                                          ** 5,280 Ft in a Mile.  Square Mile = 5,280 X 5,280 Ft.
                 = 27,878,400 square feet per square Mile
                 = 27,878,400 X 69,903 = 1,948,783,795,000 square feet 



Area of football field  = 120 Yd by 53 & 1/3 Yd                                    ** Football field length includes end zones 10 Yds each
                                      = 360 Ft by 160 Ft                                                ** 3 feet per yard ** 
                                      = 57,600 Square feet in a football field
 


Number of football fields in Oklahoma  =  1,948,783,795,000/ 57,600
                                                                     =  33,833,052 Football fields


At a rate of one football field per second it would take 33,833,052 seconds to level Oklahoma.



Number of seconds per year  = 60 seconds X 60 Minutes X 24 Hours X 365 Days

                                                    = 31,536,000 seconds in one year

Years to level Oklahoma  =  33,833,052/ 31,536,000
                                             =  1.072839041  Years

                                            =  6,782,327 x 27,878,400 square feet
                                            =  18,908,042,500,000  square feet
                                          
Number of football fields in South America = 18,908,042,500,00 / 57,600
