What is the formula for calculating the volume of an octagonal prism?

Calculating the volume (V) of an octagonal prism involves finding the area (A) of the octagon that is an end (or base), and then simply multiplying it by the length (L) of the prism. The area of an octagon with a side of length s is given by this formula: Aoctagon = 2 (1 + sqrt 2) s2 or about 4.8284 s2 If we take that and multiply it by the length of the prism, we should arrive at the volume thus: Voctagonal prism = L x Aoctagon


How many edges has a decahedron?

The correct spelling is Dodecahedron and it has 30 edges.* * * * *The correct spelling for a shape with 12 faces is, indeed, dodecahedron. But the question is about a shape with 10 faces, for which the spelling IS correct.Unfortunately, that is as far as we can go. There are many possible configurations for a decahedron and they have different numbers of edges:For example:A nonagon based pyramid: 18 edgesAn octagonal prism : 24 edgesA pentagonal dipyramid: 15 edges.


What is the volume of the prism in cubic inches?

To find the volume of a prism, multiply the area of the base by the height of the prism. The volume is typically expressed in cubic units. So, if the prism is in inches, the volume would be in cubic inches.


What is a hollow prism?

A hollow prism is a prism that is empty inside, without any material filling. It lacks the usual glass or crystal structure of a standard prism. It primarily functions to refract or reflect light due to its geometric shape.


What is the formula for the volume of a prism?

The formula for the volume of a prism is V = Bh, where V is the volume, B is the area of the base of the prism, and h is the height of the prism.
