Given that is the base's area and is the height of a pyramid, the volume of a pyramid is: [25] =. The volume of a pyramid was recorded back in ancient Egypt, where they calculated the volume of a square frustum , suggesting they acquainted the volume of a square pyramid. [ 26 ]
The formula for the volume of a pyramidal square frustum was ... the lateral surface area is ... Derivation of formula for the volume of frustums of pyramid and ...
More generally, the lateral surface area of a prism is the sum of the areas of the sides of the prism. [1] This lateral surface area can be calculated by multiplying the perimeter of the base by the height of the prism. [2] For a right circular cylinder of radius r and height h, the lateral area is the area of the side surface of the cylinder ...
In geometry, a square pyramid is a pyramid with a square base, having a total of five faces. If the apex of the pyramid is directly above the center of the square, it is a right square pyramid with four isosceles triangles; otherwise, it is an oblique square pyramid. When all of the pyramid's edges are equal in length, its triangles are all ...

The volume of a tetrahedron can be obtained in many ways. It can be given by using the formula of the pyramid's volume: =. where is the base' area and is the height from the base to the apex. This applies for each of the four choices of the base, so the distances from the apices to the opposite faces are inversely proportional to the areas of ...
A pentagonal pyramid has six vertices, ten edges, and six faces. One of its faces is pentagon, a base of the pyramid; five others are triangles. [2] Five of the edges make up the pentagon by connecting its five vertices, and the other five edges are known as the lateral edges of the pyramid, meeting at the sixth vertex called the apex. [3]
