## How do you find the volume of a octagonal 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 a octagonal based prism?**

An octagonal prism is a three dimensional polyhedron bounded by 2 octagonal bases and 8 square sides. It has 24 edges and 16 vertices.

**How do you find the surface area of a octagon?**

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.

### What is the volume of a octagonal?

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)

**How do you draw an octagonal prism net?**

The net of a octagonal prism consists of two octagons and eight rectangles. The octagons are the bases of the prism and the rectangles are lateral faces. Rotate the prism direction by clicking and dragging the shape or by clicking on the arrows in the corners. Stop the rotation by clicking on the shape itself.

**How do you find the surface area of an octagonal blender?**

Area of an Octagon

- There are several ways to calculate the area of octagon.
- The octagon can be conceptualized as small eight isosceles triangles sharing a common apex.
- Consider one of the triangles.
- Area of the octagon is given as 8 x Area of Triangle.
- 2 cos²θ = 1+ cos 2θ
- Area of the octagon = 8 x Area of Triangle.

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

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 to calculate the surface area of an octogonal prism?**

Trigonometry Function Calculator Pythagorean Identity Calculator Octogonal prism Area, Volume, Surface Area Calculation Side Length (a) Height (l) Distance (d) Area (A) Volume (V) Surface Area (SA) Formula : Area (A) = 2 × a × d Volume(V) = A × l Surface Area (SA) = (2 × A) + (8 × a × l) Where, a = Side Length l = Height d = Distance

**What are the two faces of an octagonal prism?**

The two faces at either end are octagons and the rest of the faces are rectangular. where a is the base length, h is height and d is the distance of octagonal prism.

### What should my child know about the octagonal prism?

The octagonal prism is, like the hexagonal prism, not a commonly studied prism at elementary level. At the very most, your child will have to be able to identify the shape and count its vertices and edges.

**Can my child calculate the volume and surface area of an octagon?**

At the very most, your child will have to be able to identify the shape and count its vertices and edges. Your child will most likely never have to calculate either the volume or the surface area UNLESS.. a value for the area of the octagon is given.
