How do you estimate that carrot has more mass?

To estimate that a carrot has more mass, you can compare it to a similar object with a known mass, like a potato. By holding both objects, you can gauge their weight by feel. Additionally, using a kitchen scale would provide a precise measurement of mass in grams or ounces, allowing for a direct comparison. If the carrot weighs more than the potato, you can conclude that it has more mass.
