5 mm thick square steel, 140 mm long, how much does it weigh?
Honey! Hello, I'm glad to answer your question. Square steel with a thickness of 5mm, 140mm, and a length of 6m: theoretical weight calculation formula of square pipe 4x wall thickness x (side length-wall thickness) x7. When the side length and wall thickness are in millimeters, directly substitute the numerical value into the above formula to get the weight of square pipe per meter, in grams. For example, 30×30×2. 5 mm square pipe, according to the above formula, its weight per meter can be calculated as 4x2. 5x(30-2 .5)x7 .85=275x7 .85=2 158。 75 grams, about 2. 16kg When the wall thickness and side length are in millimeters, 4x wall thickness x (side length-wall thickness) Calculate the square pipe volume per meter length, in cubic centimeters, and then multiply it by the specific gravity of iron 7 per cubic centimeter. 85 grams, which is the weight grams per meter of square pipe. According to the conditions you gave above (140-5. 0)*4*5。 0*7。 85*6= 127。 17kg
