An 8″ diameter duct is being fabricated and the duct will be joined using a 1/4″ wide groove seam that will be pounded together to seal the duct. When calculating the material, remember to allow for bends needed to make the j oints. Each duct section is 36″ long. How many 3` long duct sections can be cut from a 4` x 10` sheet?
