How many cups brown sugar in a 5 lb bag?

Here's how to calculate that:

* 1 cup of packed brown sugar weighs approximately 0.42 pounds.

* Divide the total weight of the bag (5 lbs) by the weight of one cup (0.42 lbs): 5 lbs / 0.42 lbs/cup = 11.9 cups

* Round up to the nearest whole cup to account for variations in packing.

Important Note: This is an approximation, as the actual amount of brown sugar in a bag can vary slightly depending on the brand and packing density.
