A square steel, 2 meters long, with a cross-sectional area of 4 square centimeters. How much does this square steel weigh? 1000 How many kilograms does this steel weigh?
4 square centimeters =0.04 square meters
The volume of this square steel is v = 2 * 0.04 = 0.08m3.
Because 1 m3 steel weighs 7.8 kg.
So the weight of this square steel is: G=0.08*7.8=0.624 kg.
That is, the weight of 1000 pieces of such steel is: G= 1000*0.624=624 kg.
