Octahedron

All walls of regular octahedron are identical equilateral triangles. ABCDEF octahedron edges have a length d = 6 cm. Calculate the surface area and volume of this octahedron.

Correct result:

S =  124.7077 cm2
V =  101.8234 cm3

Solution:

d=6 S1=3/4 d2=3/4 62=9 315.5885 S=8 S1=8 15.5885=72 3=124.7077 cm2
V=2/3 d3=2/3 63=72 2=101.8234 cm3



We would be very happy if you find an error in the example, spelling mistakes, or inaccuracies, and please send it to us. We thank you!
