the total estimated nappy use.=10,500,000
given that on an average the average baby uses 3528 napkins.
in a particular year 2014, the number of births were 299697 in new south wales.
rounding off the number of births to the nearest hundred thousand we have
no of birtsh = 300000
also rounding off the average usage to nearst thousand we get
average use of a baby = 3500
hence total number of nappy estimated to be used = 3500x300000
answer is 10,500,000 nappies
