How do you find the volume of a octagon prism?
To calculate the area of the octagon (base area), multiply the perimeter of the octagon by its apothem and divide by two. Then to get the volume of the octagonal prism you need to multiply the result by the length of the prism.
What is the formula for volume of a octagon?
Multiply the length of one side of the octagon by itself. Multiply the number you calculated in Step 1 by 4.8284. This is the area of the octagon. Multiply the area of the octagon by its depth to find its volume.
How do you find the volume of a regular octagonal 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 formula of octagonal?
In geometry, the octagon is a polygon with 8 sides. If the lengths of all the sides and the measurement of all the angles are equal, the octagon is called a regular octagon….Octagon Formulas.
| Formulas for Octagon | |
|---|---|
| Area of an Octagon | 2a2(1+√2) |
| Perimeter of an Octagon | 8a |
What is the area of octagonal surface?
If the shape is a polygon and it has eight sides, we call it an octagon. To find the area of an octagon we use the following formula. Area of octagon formula = 2 × s2 × (1+√2). Where “s” denotes the length of the side of an octagon.
How many vertices does a octagonal prism have?

Answer: An octagonal prism has 10 faces, 24 edges, and 16 vertices.
How do you find an octagonal area?
What is the apothem of a regular octagon?
The apothem (sometimes abbreviated as apo) of a regular polygon is a line segment from the center to the midpoint of one of its sides. Equivalently, it is the line drawn from the center of the polygon that is perpendicular to one of its sides.
How do you calculate the volume of an octagonal prism?
First write the given dimensions of the prism.
What is the formula for the volume of a prism?
a = Apothem length of the pentagonal prism
How do you find the volume of the prism?
– Write down the formula for calculating the volume of a trapezoidal prism. The formula is: V = [1/2 x (base1 + base2) x height] x height of the prism. – Find the area of the trapezoidal base face. – Find the height of the trapezoidal prism. – Multiply the area of the base face times the height. – State your answer in cubic units.
How do you calculate the volume of an octagon?
– Short diagonals, for example, AG, FH, or CE; – Medium diagonals, such as AF or BE (also called the height of an octagon); and – Long diagonals, for example, AE or BF.
