To calculate the weight of an 8mm diameter steel rod, use the formula: weight = volume x density.

• Calculate the volume of the rod using the formula: volume = π x (diameter/2)^2 x length

• Find the density of steel, which is typically around 7850 kg/m^3

• Multiply the volume by the density to get the weight of the rod
