Question 1056006
Identical to #1056003


x and y are the uncut, unfolded cardboard dimensions.


Cutting out the square shaped corners of 4cm sides and folding produces a base area of  (x-2*4) and (y-2*4)  and this base area is  {{{(x-8)(y-8)}}}.  You are given in description that {{{xy=1008}}}.


Also is given the volume of the resulting rectangular box, of last dimension 4.


Volume is  {{{4(x-8)(y-8)=2240}}}.


Solve this system for x and y.
{{{system(4(x-8)(y-8)=2240,xy=1008)}}}
which is equivalent to more simplified system of
{{{system((x-8)(y-8)=560,xy=1008)}}}.
If you are able to handle the algebra steps from here, then you can finish.
