Answer
200 ft: $\approx228.25$, 400 ft: $\approx456.51$, 600 ft: $\approx684.76$
The shortest total wire length required is $\approx684.75$ft
Work Step by Step
To solve this problem, plug each value of h into the given formula to find the length of the wires. To find the shortest total wire length, you take the height with the smallest amount of wire used (per wire), in this case 200 ft, and then multiply that by three, because in the problem it states that 3 wires are attached.
