6. A solid iron pole consists of a cylinder of height 220 cm and base diameter 24 cm, which is surmounted by another cylinder of height 60 cm and radius 8 cm. Find the mass of the pole, given that 1 cm 3 of iron has approximately 8g mass. (Use )
The pole can be divided into one large cylinder and one small cylinder.
Thus, volume of pole = volume of large cylinder + volume of small cylinder
