The cross section of a pyramid shrinks from the shape of the base down to a point as you move along its axis from the The uniform cross section of the given cylinder is a circle. In short to

What happens when you slice vertically into a rectangular pyramid? What kind of geometric shape results? So I have a three-dimensional solid right over here. And I want to imagine what type of a shape I would get if I were to make a vertical cut.

The cross section of this circular cylinder is a circle We don’t draw the rest of the object, just the shape made when you cut through. Example: The cross section of a rectangular pyramid is a rectangle Cross sections are usually parallel to the base likecan be

In geometry, a pyramid is a polyhedron formed by connecting a polygonal base and a point, called the apex. Each base edge and apex form a triangle, called a lateral face. It is a conic solid with polygonal base. A pyramid with an n-sided base has n + 1 vertices, n + 1 faces, and 2n edges. All pyramids are self-dual. A right pyramid has its
