Weight of a watermelon is 1 kg.
What is the total weight of 7 such watermelons?
Write your answer in grams.

Weight of each watermelon = 1 kg
Weight of 7 such watermelons = 7 × 1 kg
= 7 kg

We know that,
1 kg = 1000 g
So,
7 kg = 7 × 1000 g
= 7000 g

Thus, the weight of 7 such watermelons is 7000 g.
