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.
In order to find out weight, you should know the volume and density of the steel plate and then multiply volume with density i.e. volume x density.
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
