Definition

The height of a solid figure is the length of a perpendicular from the base to the point or points most distant from it.


Height of Parallelepiped

The height of a parallelepiped is the length of the perpendicular from the plane of the base to the plane opposite.

In the above diagram, $h$ is the height of the parallelepiped whose base is $AB$.


Height of Prism

The height of a prism is the length of the perpendicular between the bases of the prism.

In the above diagram, the distance $h$ is the height of the prism $AJ$.


Height of Pyramid

The height of a pyramid is the length of the perpendicular from the plane of the base to its apex.

In the above diagram, $h$ is the height.


Height of Cone

Let a perpendicular $AE$ be dropped from the apex of a cone to the plane containing its base.

The length $h$ of the line $AC$ is the height of the cone.


Height of Cylinder

The height of a cylinder is the length of a line segment drawn perpendicular to the base and its opposite plane.


In the above diagram, $h$ is the height of the cylinder $ACBDFE$.
