To find the weight of the rod, take its volume ( pi * radius2 * length for a cylindrical rod, make sure height and radius are the same unit) and multiply by the substance's density. In this case, assuming the diameter is 20 mm, 3.14 * 102 (the radius) * 1000 (1 meter = 1,000 mm) = 314,000 cubic centimeters. Steel's density is around 7.85 grams / cm3, so multiplying the two yields 2464900 grams or 2,464.900 kilograms (2,460 with significant digits depending on convention).

The weight of 1 foot of steel rod would depend on the diameter of the rod.
This depends on what type of steel. The density of carbon steel (one of the most common types of steel) is 7.85g/cm3Density = m/vradius of rod = 3.25mm (radius is 1/2 of diameter)3.25mm = .325 cm1 meter = 100cmvolume of cylinder = (pi)(radius)^2(h) = 33.18Density * Volume = mass7.85 * 33.18 = 260.46260.46 grams

One meter long. One meter is equal to 39.37 inches, just a little over a yard.
