How much total wire is required if the distance is 73 feet, with added tails of 5 and 3 feet?

To determine the total wire required, you start with the distance of 73 feet. This represents the length of the wire needed to cover the primary run. However, additional lengths, also known as "tails," must be factored in for proper installation and connections. In this case, there are two tails: one measuring 5 feet and the other measuring 3 feet.

To find the total wire length, you simply add these three lengths together:

73 feet (the primary distance) + 5 feet (the first tail) + 3 feet (the second tail) = 81 feet.

Thus, the total wire required is 81 feet, making it the correct choice. This calculation takes into account both the required distance for electrical installation and any necessary additional lengths for making connections or securing the wire.
