<p>[QUOTE=&quot;2manybooks, post: 9924617, member: 8267&quot;]The volume of the object is approximately 38.5 cubic in (using 4&quot; height and 1.75&quot; radius). Typical concrete weighs 150 lbs/cubic ft., or 0.0868 lbs/cubic in. 38.5 x .0868 = 3.3418 lbs. Add the additional weight of the metal jacket and dirt, and you might end up with the approximate weight of 4 lbs, which might indicate it is a can or tube filled with concrete.[/QUOTE]</p><p><br /></p>
