To calculate the length of the fourth lateral edge of a pyramid with three known edges measuring 6016, 2370, and 4350, a system of equations based on the distance formula is established. The apex of the pyramid is represented by coordinates (a, b, c), while the base corners are defined in the xy-plane. By manipulating the equations derived from the distances, a unique integral value for the fourth edge, denoted as d, is determined to lie between 4350 and 6016. The discussion emphasizes solving the equations by subtracting pairs to simplify the calculations. Ultimately, the method aims to isolate d for a precise solution.
