Flat Plate Calculator

metal weight calculator - flat plate

The volume of a flat plate = length × breadth × thickness
V = L × B × t
Let us consider a flat plate of length 500 mm = 0.5 m , breadth 200 mm = 0.200 m and thickness 2 mm = 0.002 m
Hence, Volume of a flat plate = L × B × t = 0.5 × 0.200 × 0.002 = 0.0002 m3
So, mass of flat plate = density × volume = 7900 × 0.0002 = 1.58 kg
Similarly, we can calculate the mass of rectangular bars of different dimensions.
