Question

A fluorite 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

Answer 1

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
