Hexagonal Pyramid
A hexagonal pyramid is a different kind of pyramid that exists. A hexagonal pyramid has the base in the shape of a hexagon along with isosceles triangles as the faces that combine the pyramid together at the apex. Let us learn more about the concept of a hexagonal pyramid in this article.

Hexagonal Pyramid Definition
A hexagonal pyramid is a 3D shaped pyramid that has the base shaped like a hexagon along with the sides or faces in the shape of isosceles triangles that form the hexagonal pyramid at the apex or the top of the pyramid. A hexagonal pyramid has a base with 6 sides along with 6 isosceles triangular lateral faces. The other name for a hexagonal pyramid is Heptahedron. A hexagonal pyramid consists of 7 faces, 12 edges, and 7 vertices. An image of a hexagonal pyramid is given below for your reference.
Hexagonal Pyramid Properties
Just like any other pyramid, a hexagonal pyramid also has unique properties that differentiate it from the other pyramids. Let's see what are those properties:
 A hexagonal pyramid has the base of a polygonshaped figure known as a hexagon
 A hexagonal pyramid consists of 6 isosceles triangles as the faces that are erected against the base and combined to the apex
 There are 7 vertices in total in a hexagonal pyramid where 6 is at the base of the pyramid and one at the top
 A hexagonal pyramid has 12 edges i.e. 6 connecting the triangle edges to the main vertex and the 6 edges of the base
 In total, a hexagonal pyramid has 7 faces, one for each side of the triangle along with one base
Volume of Hexagonal Pyramid
To calculate the volume of a hexagonal pyramid, we need to know three major aspects of the hexagonal pyramid i.e. the apothem which is measured from the center of the base to any point on the side of the base, second is the length of the base, and third is the height which is the height of the pyramid from the apex to the base. Hence, the formula to calculate the hexagonal pyramid volume is:
Volume of Hexagonal Pyramid = (abh) cubic units
Where,
 a is the apothem of the pyramid
 b is the base
 h is the height
When the apothem of the hexagonal pyramid is not mentioned and when the triangles are equilateral triangles, we can use another alternative formula which is:
Volume of hexagonal Pyramid = (√3/2) × a^{2} × h cubic units, where a is the side of the base and h is the height of the hexagonal pyramid
Surface Area of a Hexagonal Pyramid
Before we calculate the surface area of a hexagonal pyramid, we also need to know its base. The surface area of the hexagonal pyramid can be calculated when we have the slant height of the pyramid which is the height from the apex to any point on the boundary of the base of the pyramid. Hence, let us see both the formula of the hexagonal pyramid  base area and surface area.
Base Area of Hexagonal Pyramid = 3ab square units
Surface Area of Hexagonal Pyramid = (3ab + 3bs) square units
Where,
 a is the apothem of the pyramid
 b is the base
 s is the slant height of the pyramid
Hexagonal Pyramid Net
A hexagonal pyramid consists of 7 faces, 7 vertices, and 12 edges. The net of the hexagonal pyramid is formed with a hexagonshaped base consists of 6 sides along which 6 triangles are formed by connecting the edges of the base. These triangles are called the lateral faces of the pyramid. When the pyramid is flattened, the 6 triangles and one hexagon base are seen i.e 6 faces and one face in the base.

Examples on Hexagonal Pyramid

Example 1: Find the volume of a hexagonal pyramid with apothem length of 6 units, base length as 9 units, and height as 15 units.
Solution: Given is, a = 6, b = 9, and h = 15. Let's place the values in the formula of the volume.
Hexagonal Pyramid Volume = abh cubic units
Volume = 6 × 9 × 15
Volume = 810 units^{3}
Therefore, the volume of the given hexagonal pyramid is 810 units^{3}.

Example 2: What would be the base area and the surface area of a hexagonal pyramid, if it has an apothem length of 4 units, base length as 9 units, and slant height as 14 units?
Solution: Given is a = 4, b = 9, and s = 14
Let's calculate the base area of the hexagonal pyramid first,
Base Area = 3ab square units
Base Area = 3 × 4 × 9
Base Area = 108 units^{2}
Next, let's calculate the surface area of the hexagonal pyramid,
Surface Area = 3ab + 3bs square units
Surface Area = 3 × 4 × 9 + 3 × 9 × 14
Surface Area = 108 + 378
Surface Area = 486 units^{2}
Therefore, the surface area of the pyramid is 486 units^{2 }and the base area is 108 units^{2}.
