Given -
Length of mild steel plate = 2 meter
Breadth of mild steel plate = 2 meter
Thickness or Height of mild steel plate = 20 mm
Volume of mild steel plate = Length X Breadth X Height
= 2 x 2 x 20 mm
= 2 x 2 x 0.02 m
Volume of mild plate = 0.08 m3
Weight mild steel plate = Volume X Density
= 0.08 x 7850……….(Density of steel is 7850 kg/m3)
= 628 kg
