In string theory, as I understand it, a frequency between two points creates a particle, different frequencies make different particles.

If say the points were arranged in a cube there would be 8 points with twelve strings between them, would this lead to twelve particles or would one particle be produced from the harmonic frequency of the entire cube?

Second question, what is the explanation for the points, are they just an imaginary point at the end of each string or do they have attractive or repulsive effects? Is the frequency of the string a product of say a + value at one end and a - value at the other?

Last question, If the strings are one dimensional would the cube described above be 3 dimensional?

Hope somene can help
