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?

576 cm2

- 10.4 cm

998.4 cm2

499.2 cm2

12 cm

1,152 cm

12 cm

12 cm

499.2 cm²

Step-by-step explanation:

See attachment for the figure.

The area of a triangle is given by

A = 1/2bh

A = 1/2(12)(10.4)

A = 62.4 cm²

Then, take that area and multiply it by the number of faces. In this problem, there are 8.

62.4 × 8 = 499.2 cm²
