What solid has a triangular cross section when the cross section is taken perpendicular to the base?
A solid with a triangular cross section when the cross section is taken parallel to the base could be either a triangular prism, a triangular pyramid, or a triangular frustrum.. I've been sitting here trying to convince myself (without actually bearing down and trying to prove it mathematically) that any cross section of a regular tetrahedron (a special case of triangular pyramid) taken perpendicularly to the base is a triangle, and I THINK this is the case, but as I said I certainly haven't rigorously proven it; I'm just unable to come up with any obvious situation where this is not true.

What is a solid oval called?
A solid oval is called an ellipsoid. It is a three-dimensional shape that resembles a stretched circle. It has an oval cross-section in all planes perpendicular to its main axis.
What is the intersection of a plane and a solid?
It is a cross section.
What is a circle called in a solid?

What does cross-section mean?
When a 3-dimensional (solid) object is cut by a plane, the 2-dimensional shape made where the solid object and the plane meet is the cross section.
What is known as full section of solid?
A full section of a solid is when a plane cuts through the entire solid, revealing its complete cross-section. This is helpful for analyzing the internal structure and geometry of the solid.
What is the definition of a uniform cross-section?
A Uniform Cross Section is the cross section of the solid, parallel to base, such that the resulting figure has the same shape and size as that of the base of the figure.More about Uniform Cross SectionSolids like pyramids and cones have slant heights and hence do not have uniform cross section.Examples of Uniform Cross SectionThe uniform cross section of the given prism is a square.The uniform cross section of the given cylinder is a circle.In short to say, uniform cross-section are when you dissect a 3D solid and you get all same shape (uniform).
What do you notice about the cross section of a solid sphere?
Every section of a solid sphere is a filled-in circle, i.e. a disk with zero thickness.
How can you the volume of a rectangular solid?
