Calle smashes the side of his box
Calle's initial plan is to cut the block into four smaller triangular blocks, which would then each be the correct size to fit through the hole.
After a pause to think it over, he fetches a hand saw and begins making measurements.
As he breaks out the ruler, he notes to the audience that it's going to be such boring TV, that they may as well switch it off now.
He makes it halfway through his first cut before abruptly pausing to tap on the side of the box, and then asking if there's a sledgehammer.
Calle then smashes a hole through the side of the box, then reaches his arm through the small triangular hole on the top, in order to pull the triangle into the box through its now wide-open side.
He completes the task in 14 minutes and 56 seconds, and earns fourth place.
