A cube and a truncated cone are shown below. The cube has dimensions 10 × 10 × 10 units. The truncated cone has a base diameter of 12 units, height of 11 units and top diameter of 6 units. Imagine these two solids are intersecting while positioned coaxially on the same base. Further imagine the cube vanishes completely along with the intersected portion of the truncated cone. What remains? [Figure: see page 27 of source PDF]
