Which of the following is closest to the weight of a watermelon? One-fifth kilogram, five kilograms, 30 kilograms, 50 kilograms, or 60 kilograms.

One kilogram and one kilogram is about the weight of a one-litre bottle of soda. We’re trying to estimate the weight of a watermelon. Would a watermelon weigh one-fifth of a kilogram? That would be less than a one-litre bottle of soda. And that is not heavy enough.

How about five kilograms? Would a watermelon weigh the amount of five soda bottles? It does seem like that could be an option. Would a watermelon weigh 30 kilograms, the amount of 30 one-litre bottles of soda? That is way too much, which means 50 kilograms and 60 kilograms will be way too much to measure watermelon. The only reasonable weight measurement given is five kilograms. It’s reasonable that a watermelon would weigh five kilograms.
