A Question that I need help for
A cube has its vertex named A,B,C,D,E,F,G,H. All of them are real positive numbers. A near sum is the sum of all numbers of the vertexes that connects to the original vertex. The value of the near sums are (3,6,9,12,15,18,21,24). If the value of the near sum of A is 1, then what is the value of the near sum of F?
