Answer:
We conclude that the volume of a regular octahedron will be:
cm
Step-by-step explanation:
Given
The length of one of the side or edge of a regular octahedron = a = 4 cm
To determine
The volume of a regular octahedron = V
Using the formula to determine the volume of a regular octahedron

substituting a = 4 in the volume equation

∵ 4³ = 64
cm
Therefore, we conclude that the volume of a regular octahedron will be:
cm
