I'm not blaming anyone in particular... but building a cube dispenser above a pit was an interesting decision.
What do we have here?
A cube in a pit.
If the last chamber didn't make it clear enough, there's no fall damage in this game.
Now I'm stuck in a pit!
If you didn't see it earlier, there's an orange portal on the wall near the button you need to press.
How does that help me?
Don't forget - you can shoot portals on any valid surface.
Shoot a portal onto the floor, grab the cube, and jump through it. You can then activate the button and proceed to the exit.
