Explanation:

Step1: Understand mass - unit relationship

1 kilogram = 1000 grams. A skateboard is a relatively large and heavy object compared to something that would be measured in grams. 3 grams is an extremely small mass, like the mass of a few paper - clips.

Step2: Consider the nature of a skateboard

Skateboards are made of wood, trucks, and wheels, and have a noticeable weight. They are typically measured in kilograms. 3 kilograms is a more reasonable estimate for the mass of a skateboard.

3 kilograms
