A storage room measures 400 inches in length, 200 inches in
width and 200 inches in height. It needs to be modified, by
extending its length, to hold at least 3000 20-in cube boxes.
To meet this goal, what is the minimal length needs to be
added? Need at least__inches more in length for the
storage room.

the total estimated nappy use.=10,500,000

step-by-step explanation:

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

= 10,500,000

answer is 10,500,000 nappies

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
