A corroded metal gusset plate was found on a bridge. It was estimated that the original area of the plate was 750 cm2 and that approximately 2.5 kg had corroded away during use. Assuming a corrosion penetration rate of 0.5 mm/year for this metal, estimate the time since construction of the bridge. The density of the alloy is 10 g/cm3 .
