Single Aluminum (Al) Density Cube for density investigation.
Sides 0.8" (19mm) long.
Where measurements are in both metric and imperial, the metric measurements are generally more accurate (the imperial are provided as a general reference).
These density cubes are designed to be used in an educational setting and are not fabricated using ultra high precision machining. Expect tolerances in the +/- 5% range of any stated dimensions (although they are generally much tighter).
