Nitpick this: 8-) Steel is just under 500lbs/cubic foot (1728 cu ins) If that is 3" x 12ft bar, it comes out to just over 0.5cubic foot (1018 cu ins) If it's 2" x 12ft, then its about 0.25cubic foot (453 cu ins) I leave the rest of the arithmetic to you. -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
