Yes you can, and you
WILL!!!
Might not be the way others did it, but it works for me.
Try and get to a position as shown in the picture below. Use the plasma block and the coins to get the boulders there.
Then the boulders follow the red arrow; first boulder over; then time it right for the second boulder. get the timing right and you can run straight over, pushing the box as you go; thus trapping the nasty ghosts.
After that, the rest is easy.
Now get out there and do it!!! The Void is waiting for you.
