The box is actually just two peoples of cardboard that are carefully placed on top of one another and folded.
But when looked at from a distance, the cardboard looks like a 3D box because of the way our brains process images and spatial awareness.
It's called "reverse perspective" and it's a trick used in many optical illusions.
The Neural Correlate Society, which awarded the illusion, researches how these brain teasers play tricks on us.

In the video's description, the science behind the illusion is explained: "The two pieces of the box (front and back) visually fuse together to create what appears to be a normal ordinary box.
