AA hexagonal prism is a three-dimensional solid consisting of two identical hexagonal bases joined together by six lateral faces. The lateral faces are rectangular in shape. It has 8 faces, 18 edges, and 12 vertices.

The shape of pencils, weights, and nuts are some real-life examples of a hexagonal prism.

A 2-dimensional net can be used to construct a hexagonal prism to understand the shape.

A hexagonal prism can be **regular** or **irregular** based on the uniformity of its cross-section. It can also be **right** or **oblique**, depending on the alignment of its bases.

**Regular Hexagonal Prism**â€“ Its 2 bases are regular hexagons.**Irregular Hexagonal Prism**â€“ Its 2 bases are not regular hexagons.

**Right Hexagonal Prism**â€“ It has all the lateral faces perpendicular to the bases. Thus every lateral face is rectangular.**Oblique Hexagonal Prism**â€“ Its lateral faces are not perpendicular to its bases. So, every lateral face is parallelogram-shaped.

Like all other polyhedrons, we can calculate the surface area and volume of a hexagonal prism.

The formula is given below:

**Total Surface Area ( TSA) = 6ab + 6bh**, here

As we know,

**Total Surface Area ( TSA) = 2 Ã— Base Area + Base Perimeter Ã— height**

Also,

Lateral Surface Area (*LSA*) is the sum of the areas of all the faces except the bases.

âˆ´ *LSA* = Base Perimeter Ã— height

Here, Base Perimeter = 6b

âˆ´ *TSA***= 6 ab + LSA, **here

Let us solve an example to understand the concept better.

**Find the lateral and total surface area of a hexagonal prism with a base edge of 9 cm, an apothem of 7.79 cm, Â and a height of 9.5 cm.**

Solution:

As we know,

Lateral Area (*LSA*) = 6*bh*, here *b* = 9 cm, *h* = 9.5 cm

âˆ´*LSA *=6 Ã— 9 Ã— 9.5

= 513 cm^{2}

Total Surface Area (*TSA*) = 6*ab* + *LSA*, *Â Â *here *a* = 7.79 cm, *b* = 9 cm, *h* = 9.5 cm

âˆ´ *TSA* = 6 Ã— 7.79 Ã— 9 + 513

= 933.66cm^{2}

The formula is given below:

**Volume ( V) = 3abh, **here

Let us solve an example to understand the concept better.

**Find the volume of a hexagonal prism with a base edge of 7 cm, an apothem of 6.06 cm, and a height of 4 cm.**

Solution:

As we know,

Volume (*V*) = 3*abh, *here *a* = 6.06 cm, *b* = 7 cm, *h* = 4 cm

âˆ´*V* = 3 Ã— 6.06 Ã— 7 Ã— 4

= 509.04 cm^{3}
