8. Emily forms a closed box from a rectangular piece of
cardboard by cutting along solid lines and folding
along dashed segments. She glues the square corner
flaps of side length x to the sides they overlap when
they are folded. She then folds the right side of the
pattern over the left side. The narrow rectangle in the
center of the pattern forms a side of the box. To close
the lid, Emily tucks the sides of the lid inside the sidesp
of the bottom. Find a polynomial function for the volume.
What is the maximum volume to the nearest cubic inch?
