Question

i only gwt four trys please and thank you for helping

Enter your answer in the provided box. A construction company is installing an iron culvert (a long cylindrical tube) that is 35.0 m long with a radius of 0.600 m. To prevent corrosion, the culvert must be galvanized. This process is carried out by first passing an iron sheet of appropriate dimensions through an electrolytic cell containing Zn2+ ions, using graphite as the anode and the iron sheet as the cathode. If the voltage is 3.26 V, what is the cost of electricity for depositing a layer 0.200 mm thick if the efficiency of the process is 95.0 percent? The electricity rate is S 0.120 per kilowatt hour (kWh), where 1 W=1J/s and the density of Zn is 7.14 g/cm?
