A cube has an edge lenght of 9 centimeters

72Cm

Step-by-step explanation:

The perimeter is 4 times 1 side

currently, it is 9 times 4 or 36

increased by 3

I think y mean times 3

so 9*3=27

new perimeter is 27*4=108

how much larger is it?

108-36=72

it is 72cm larger

it is the first answer

(it isn't cm² because that is for area and we are calculating perimeter)

the distance between point a and point b is 6 units

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
