Giant Cube Dissection

These seven pieces fit together to make a large cube.
How it works
This Soma Cube puzzle’s first challenge is to use seven different cube-based puzzle pieces to build a giant cube. You can also try building other suggested structures using the same seven puzzle pieces.
Background
There are actually 240 different ways of assembling the large cube in this Soma cube puzzle. This puzzle was born when Piet Hein thought about how to glue small cubes together to make larger pieces. After experimenting, Hein found that twelve different-shaped pieces can be made using only four small cubes. He also discovered that only seven pieces are needed to build a large cube.
