Then, if "efficiency" happened to mean what we guessed, you could do the calculation. That formula you mentioned, "multiply the mass and the distance, and then divide that by the length of the arm", gives some mass as the answer. Your answer probably has some units, maybe kilograms. For answers with units, the units are very important.
