Suppose we want to connect the buildings at a corporate campus with skybridges. The cost of each possible skybridge connection is shown in the diagram: A 2 5 4 B 2 1 F D 5 5 2 2 4 8 C 3 E 9 6 8 9 G 7 H We want them built in such a way that a person can get to any building from any other using the skybridges. Find the cheapest way to make this happen. What is the minimum cost? Hint: solve it on paper without using Excel
