By watching this exclusive construction video, you will be familiar with the method for measuring the weight of mild steel plate. The video is based on a MS square shaped steel plate and length of that plate is 1 meter, breadth is 1 meter and its thickness is 10 mm or 0.01 meter.
Formula for detecting the volume = Length x Breadth x Height i.e. 1 x 1 x 0.01 m = 0.01 m3
Density of steel = 7850 kg/m3
Therefore, weight will be = 0.01 x 7850 = 78.5 kg
