When a rectangle is rotated around an axis that bisects it (either the axis along its length or its width), it forms a cylindrical shape. This is because each point on the rectangle traces out a circular path in 3D space as it rotates around the axis, resulting in a cylinder.

So, the correct answer is:

- **cylinder**
