Plastic Storage Container

The Trunk Of My Car Is Sealed Shut, But I Can Still Get Into The Trunk From The Inside Of My Car. Now The Real Problem Is This Huge Plastic Storage Container Is Blocking Most Of The Space In The Trunk. To Make Matters Worse, The Space In My Car Which Leads To The Trunk Is Not Large Enough To Remove The Container Intact. Hopefully, I Can Just Cut Through It Since The Thing Is Empty. I Just Have No Idea What I Could Possibly Use And Any Help Would Be Very Much Appreciated.
