• Width = 100 cm
• Height (Thickness) = 2 cm

The volume would be:

Volume=200cm×100cm×2cm=40,000cm³

Then, multiply the volume by the density to get the weight:

Weight=7.85g/cm³×40,000cm3=314,000g or 314kg

2. For Cylindrical Bars (Round Bars):

For cylindrical steel bars, the formula for the volume is:

Volume=π×(Diameter​/2)²×Length

For example, if you have a 16MnCr5 steel round bar with:
