b.
83.12 oz
c.
87.79 oz
d.
109.74 oz

Answer 1

Convert each item to ounces (1 oz = 28.3495 g; 1 lb = 453.59237 g = 16 oz; 1 ton = 2000 lb).

- Cookie jar: 2115.16 g ÷ 28.3495 ≈ 74.64 oz
- Nightstand: 2.02 kg = 2020 g ÷ 28.3495 ≈ 71.26 oz
- Coat: 0.00260 ton = 0.00260·2000 lb = 5.2 lb = 5.2·16 = 83.12 oz
- Watermelon: 5.49 lb = 5.49·16 = 87.79 oz

The heaviest is the watermelon: 87.79 oz → answer c.
