Archived thread "Volumes of Regular Icosahedron and Regular Tetrahedron"

Hi,

The above-referenced thread is at this url address:

https://www.physicsforums.com/archive/t-3876

I have something to add, having worked with this structure, in a bit of a different way, however, than is spoken of in the thread. There are no dates on the entries, and the thread seems to no longer be available for comment.

Can you give me information about the thread, if it is very old, maybe it would be meaningless to even post a response...?

Yours truly,

gayla

1. What is an archived thread?

An archived thread refers to a previous discussion or conversation that has been saved or stored for future reference. It is typically found on online forums or message boards.

2. What is a regular icosahedron?

A regular icosahedron is a three-dimensional geometric shape with 20 equilateral triangular faces, 30 edges, and 12 vertices. It is one of the five regular polyhedra, also known as Platonic solids.

3. What is a regular tetrahedron?

A regular tetrahedron is a three-dimensional geometric shape with four equilateral triangular faces, six edges, and four vertices. It is also one of the five regular polyhedra.

4. How do you calculate the volume of a regular icosahedron?

The formula for calculating the volume of a regular icosahedron is V = (5/12) * √2 * a^3, where "a" represents the length of one of the edges.

5. How do you calculate the volume of a regular tetrahedron?

The formula for calculating the volume of a regular tetrahedron is V = (√2 / 12) * a^3, where "a" represents the length of one of the edges.
