A rectangular Piece of metal is 15 inches longer than it is wide. Squares with sides 3 inches long are cut from the four corners and the flaps are folded upward to form an open box. If the volume of the box is 648 in.³ what were the original dimensions of the piece of metal

you can't solve x because it is 2 linear equation and you only have one equation

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
