Depends on how big your rectangle is.
If it section is a rolled like beam,channel,square,angles&flat. weight=Length x unit weight unit weight of this section is=123kg/m^3 If it is plate or sheet weight=Length x width x thickness x 7.85(sp.gravity of steel)
unit weight of 60mm dia hallow ms pipe
ismc 200 unit weight
The CGS unit of weight (no longer used) was the gram
Density is mass per unit volume, and sometimes in some industries weight per unit volume is used. Weight per unit volume is also sometimes called specific weight. Weight and mass are not the same. Volume per unit mass is called specific volume, and is the reciprocal of density. It is not clear whether volume per unit weight can also be used as a measure of specific volume.
What is the unit weight of aluminium section and how its calculate
(Side1Xside2) x ((side1-2t)x(side2-27))*0.007850 where all dimensions are in mm & the weight is Kgs/Mtr
It depends on the material from which the box section is made.
If it section is a rolled like beam,channel,square,angles&flat. weight=Length x unit weight unit weight of this section is=123kg/m^3 If it is plate or sheet weight=Length x width x thickness x 7.85(sp.gravity of steel)
No set answer to that, as steel pipes come in various diameters and wall thicknesses. If you want to be real accurate, they also come in various steel alloys, which do have some difference in density between them.
unit weight of 60mm dia hallow ms pipe
While concrete has been used as a building material for many centuries, concrete hollow blocks have only been manufactured since the early 1900s. These blocks are used in all types of building projects.
unit weight = 10.68 (outer dia. of pipe - thickness of pipe) x thickness of pipe unit will be 'lbs/foot' 1 lbs = 0.45359237 kg and 1 foot = 0.3048 meter or 1 meter = 3.2808 feet
volume
No, you need three measurements to measure a rectangular prism.
Divide its weight by 20736 cubic units of volume.
It would be one box.
