Determine the volume of the cube and the combined volume of all the pieces.

Pieces that seem like they obviously should touch each other actually won't. As impossible as it may seem, that's part of the puzzle.

It's easier to assemble the cube on a table, where you can freely rotate it, and then place it into the base afterward.

On the bottom layer, one piece lies flat while three pieces stand upright.

Two of them stand on the tip of a single cube, while the third stands on the tip of three cubes.

The last piece lies flat on the second layer.

Solid cube

The goal of this puzzle is to fit all of the pieces inside the base. And remember the name of the puzzle—the result should be a cube with no holes. 😉
