An artist sculpts a sculpture from a block of hardwood, in stages. Initially, he carves a right cone with a height of 36 cm and a base diameter of 18 cm. Then, he removes a smaller cone from this cone, whose base diameter measures 6 cm, thus obtaining a truncated cone, as illustrated in the figure.
The type of wood used to produce this sculpture has a mass equal to 0.6 g per cubic centimeter of volume.
