Video Summary

A triangular pyramid with edges of integer lengths has known lengths for four edges. The task is to find the sum of the lengths of the other two edges, A and B. Using the triangle inequality, which states the sum of any two sides of a triangle must be greater than the third side, the inequalities for different triangle configurations in the pyramid are applied. Through these calculations, the lengths are determined to be A = 5 and B = 6. Summing these two lengths gives 11, which is the solution to the problem. The correct answer is 11.
