In the basic fiber density formula E = (F/nf - B/nb) / Af, what is the denominator?

Explanation:
The denominator is Af. In this density formula, Af serves as the area factor that converts the net quantity (the difference between F/nf and B/nb) into a density per unit area. The numerator gives the net amount after normalization, and dividing by Af scales that net value to density per area. The other options don’t fit because they aren’t the area factor shown in the expression: a constant like 1,000 isn’t part of the formula, and Ac or V represent different measures (another area or a volume) not used here.
