Beyond the table, Hal saw a small safe in the wall; above it, a shelf with a row of cubical boxes.

He pointed to the row of cubical boxes.

He approached the table and faced the open front of the cubical box.

Deliberately, he tilted back the top of the cubical box and lifted the head from its resting place.

He had been handicapped, hurling away table top and cubical box.

He raised a cubical box some six inches to a side and placed it atop the chest of books.

The cylinder was about four feet long, and the cubical box about eighteen inches on a side.

He pointed to tiny air-holes drilled in the sides of the cubical boxes.

In the center of the room, atop a raised dais, sat a large, dark, roughly cubical box.

Let us now consider a three-dimensional cubical box that has a side length L (see infinite square well).
