Question 1127949
Cardboard dimensions before cut and fold:
x+8 and x


Volume of the box formed:
{{{2(x-2*2)((x+8)-2*2)=96}}}


Simplify and solve the volume equation and evaluate x-4 and x+4.
Note that the height will be 2 cm.


{{{(x-4)(x+4)=96/2=48}}}


Notice the two binomial factors differ by 8.

{{{48=4*12}}}


Dimensions of box are   width 4 cm and length 12 cm.
