23PRACTICE PROBLEM
In a manufacturing process, optical lenses are produced from glass rods. Each lens requires a cylindrical glass rod having a diameter of 2.5 cm. If a rod with a length of 40 cm can be used to create five lenses, what is the maximum number of lenses that can be produced from a glass rod (of the same diameter) that is 20m long?
