Afluorite crystal is shaped like a regular octahedron with edges that are 2.1 inches. which of these is the volume of the fluorite crystal in cubic inches? round to the nearest hundredth

To solve this problem you must apply the proccedure shown below:

 1. You have the following information given in the problem above: The regular octahedron with edges that are 2.1 inches.

 2. Therefore, you must apply the formula for calculate the volume of a octahedron, which is:

 V=(a^3√2)/3

 3. Therefore, you have:

 V=((2.1 inches)^3√2)/3
 V=178.30 inches^3

It’s hard to understand what you put.. can you show a picture ?
