# What is the formula of area of octagonal surface?

## What is the formula of area of octagonal surface?

The most widely used formula to calculate the area of regular octagon is given as: A = 2a2 (1 + √2), where a represents the given octagon’s each side length.

## How do you find the volume of a octagonal pyramid?

The height of a pyramid is equal to the length of the line segment that’s perpendicular to the base and passes through the apex of the pyramid. We can find the volume of an octagonal pyramid using the following formulas: Volume = (B × h) / 3, where B is the area of the base. B = 2 × s2 (1 + √2)

## What is the base of octagonal prism?

Octagon
Octagonal prism/Base shape

## How many size are there for an octagon?

eight-sided
In geometry, an octagon (from the Greek ὀκτάγωνον oktágōnon, “eight angles”) is an eight-sided polygon or 8-gon.

## How many sides has an octagonal prism?

8
In geometry, the octagonal prism is the sixth in an infinite set of prisms, formed by square sides and two regular octagon caps. If faces are all regular, it is a semiregular polyhedron….Octagonal prism.

## What is the diameter of an octagon?

I assume you mean a regular octagon where all the sides have the same length and all the angles have the same measure. d = (1 + √2) × 60 = 144.85 feet.

## How many sides are there for an octagon 8?

In geometry, an octagon (from the Greek ὀκτάγωνον oktágōnon, “eight angles”) is an eight-sided polygon or 8-gon….Octagon.
