If it's a regular octahedron, then you can calculate it using the formula
where
is the length of the edge.
If it's not regular, you have to calculate the area of each side individually.
Step-by-step explanation:
two sides of length =0.6 and 1.6
lengths for the third side,X =?
= 0.6+1.6=2.2
lengths for the third side of X=2.2
