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)
The weight of a hollow MS (mild steel) pipe is determined by its dimensions and material density. You can calculate the weight using the formula: weight (kg) = (outer diameter - inner diameter) x inner diameter x length x density of MS. The specific density of MS used will affect the weight of the pipe.
The unit for weight in physics is the newton (N).
The unit weight of ISMC 200 is approximately 24.2 kg/m.
Since a weight is a force, the unit for force, i.e. the newton, is used.
The unit weight of RHS (Rectangular Hollow Section) 150x100x6 is approximately 33.2 kg/m. This value may vary slightly depending on the specific material used in the construction of the RHS.
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.
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.
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)
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.
