Answer 1

Convert each to ounces (1 oz = 28.3495 g, 1 kg = 1000 g, 1 lb = 16 oz, 1 ton = 2000 lb).

- Cookie jar: 2115.16 g ÷ 28.3495 ≈ 74.61 oz
- Watermelon: 5.49 lb × 16 = 87.84 oz
- Nightstand: 2.02 kg = 2020 g; 2020 ÷ 28.3495 ≈ 71.25 oz
- Coat: 0.00260 ton = 0.00260×2000 = 5.2 lb; 5.2×16 = 83.20 oz

The heaviest is the watermelon ≈ 87.84 oz, so choose C.
