The number of cups in five pounds of sugar can vary depending on the density and granulation of the sugar. However, as a general guideline, one pound of granulated sugar is approximately equal to 2 1/4 cups. Therefore, five pounds of sugar would be roughly equal to:
5 pounds * 2 1/4 cups/pound = 11 1/4 cups
So, approximately 11 and 1/4 cups of sugar are in five pounds. Keep in mind that this is an approximation, and the actual volume may vary slightly based on the specific type and brand of sugar used.
