Question 1120426
 a rectangular sheet of a cardboard box is 12 inches long and 8 inches wide.
 cutting identical squares from the corners and folding the sides to create an open box.
:
let x = side of the the squares that are removed
:
The dimensions of the box
(12-2x) by (8-2x), x = the depth of the box
:
Choose the depth of the required box (x), this will determine the dimensions of the box.
:
the constraints: x will have to be less than 4" because of the dimension (8-2x)
:
:
For example, assuming x=2" then dimensions: (12-2(2)) by (8-2(2)) by 2 
which is: 8" by 4" by 2"
