Commonly resistivity also known as bulk resistivity specific electrical resistivity or volume resistivity is in units of ω m which is more completely stated in units of ω m 2 m ω area length.
Volume of sheet metal formula.
304 polished stainless steel sheet.
The formula for the volume of a cuboid is l w h lwh where lis the length wis the width and his the height this video will give two examples of finding the volume of a rectangular prism.
316 316l stainless steel sheet.
304 304l stainless steel sheet.
Coining one of the three types of bending for sheet metal where the punch penetrates into the sheet metal under high tonnage forming a consistent bend.
The formula then is to multiply the three together.

Density table for commonly used sheet metal materials from the above two posts you will find the density of various metals and alloys.
When divided by the sheet thickness m the units are ω m m m m ω.
It is better to solve some formula based examples to really understand the fabrication formulas for sheet metal bend allowance ba the amount of material added to the sum of the two leg lengths to obtain the flat pattern length.
However sometimes you may want to learn the weight calculation formula and keep it in your mind here is it.
321 stainless steel sheet.
For example for an aluminum rectangular bar with a cross section of 20 mm by 30 mm and a length of 2 meters we need to calculate the volume as 20 x 30 x 2000 1 200 000 cubic millimeters or 1 200 cubic.
Width x height x length and then multiply by the density to get to the weight.
