Sphere
They would be two right triangular pyramids.
A sphere, a cone, a section of a sphere or ellipsoid, a torus (doughnut) sliced by a plane perpendicular to its axis, a paraboloid. These are some examples.
There are many possible answers: A sphere sliced by a plane. An ellipsoid with two equal radii, sliced by a plane parallel to them. A paraboloid sliced by a plane perpendicular to its axis. A cone.
The shape of the cross section depends on the 3D object being sliced. For example, if you slice through a cylinder horizontally, the cross section would be a circle. If you cut through a cube diagonally, the cross section could be a triangle or a rectangle, depending on the angle of the cut. Thus, the specific 2D shape observed in the cross section varies based on the object's geometry and the orientation of the cut.

It depends on the rock. Pumice is very weak and can be sliced through easily. Sandstone may be sliced through depending on its strength. Generally most rock types on the planet are are too hard to be sliced through with a sword.

A cone, or a parabolic section, or a section of a sphere like a hemisphere, or a torus (donut) sliced in half sideways.
The shape of a pyramid without its top is called a frustum. A frustum is formed when a pyramid is sliced parallel to its base, resulting in a truncated shape that has two parallel bases: one larger and one smaller. This geometric figure retains the original triangular faces of the pyramid, minus the apex.
The cross section of a figure is done by slicing part of the figure off a certain way. Inside the sliced area, there will be a 2-D figure. That 2-D figure is the cross section of the figure.
The resulting shape when a solid is sliced in a particular direction is called a cross-section. It represents the intersection of the solid with the slicing plane. Cross-sections can vary depending on the orientation and angle of the cut.
The samurai's blade sliced through the watermelon like butter.
A prism is a generic term which refers to a 3-dimensional object with two congruent faces which are joined together by a face or faces. A cylinder, for example, is a crystal. Furthermore, the shape of the cross section depends on the inclination of the slicing plane.
