Question

An octahedron and its net are shown below. All the faces are the same size and shape. What

is the surface area of the octahedron?​

Answer 1

2√3 x²

Explanation:

Answer 2

2√3 x²

Explanation:

Let the edge size be x.

Then each face has the area of:

• A = 1/4√3 x²

Since an octahedron has 8 sides, the total surface area is:

• A = 8*1/4√3 x² = 2√3 x²
