What is the formula to calculate cable length based on variables A, B, and C?

The correct formula to calculate cable length, represented as Length = A + B - C, is based on the context of determining the total length required for a specific installation scenario where A and B represent two contributing lengths and C accounts for a portion that needs to be subtracted from the total, perhaps due to overlap or a specific segment that does not require cabling.

In practical applications, A and B might represent distances from different points in a layout, while C might represent a length that needs to be excluded from the total calculation due to physical constraints, installation techniques, or design requirements. This formula effectively sums the two distances while accounting for the overlap or unnecessary length represented by C.

Understanding the roles of A, B, and C in this calculation helps inform technicians and engineers about the nuances of cable management in entertainment technology setups, ensuring that they can accurately calculate the necessary materials for an installation.
