11. Six pointed magic star, formed by powers.
 

This star is formed by two triangles, one is inverted in relation to the other one.
Take the numbers to the vertices and to the centre of the star, so that the result of the  multiplications and divisions of the three numbers  in the vertex of each triangle equals the base cubed.
The operations with the numbers in each of the three segments which cross the centre of the star also have to  be equal to the base cubed.
