Problems 10 and 14 compute a surface area and the volume of a frustum respectively.
From the en.wikipedia.org
He finds the volume of rectangular prisms, pyramids, and the frustum of a square pyramid.
From the en.wikipedia.org
The viewing frustum is a geometric representation of the volume visible to the virtual camera.

Other bases may be used, such as an octagon, or a frustum with star section shape more common to pandoro.
From the en.wikipedia.org
Each plane section is a floor or base of the frustum.

A bucket is an everyday example of a conical frustum.
From the en.wikipedia.org
It is instead often topped with an inverted frustum of a shallow cone or a cylindrical band of carvings.
From the en.wikipedia.org
Often, objects lie on the boundary of the viewing frustum.

- A truncated cone or pyramid; the part that is left when a cone or pyramid is cut by a plane parallel to the base and the apical part is removed
- In geometry, a frustum (plural: frusta or frustums) is the portion of a solid (normally a cone or pyramid) that lies between two parallel planes cutting it.
- (sometimes spelled frustrum) is from the Latin and means "a piece broken off". Mathematically it usually refers to a part of a solid cut off between two parallel planes, as opposed to truncated
- In 3D programming, a pyramid-like shape with its point at the "camera", pointing in the direction that you are viewing, and the base representing the far clip plane. This geometric shape contains all objects that are visible.
- Geometrically, a frustum is 3D shape; a pyramid that has the top chopped off. The view of a 3D to 2D perspective projection, from the eye through the plane of projection has the shape of a frustum.
- The view volume warped by perspective division.
