Answer
0.48 kg

The correct answer is 0.48 kg — Convert to kilograms: 480 g ÷ 1000 = 0.48 kg.

Step-by-step solution

  1. Weight of leaves = 24 × 15 g = 360 g.
  2. Weight of twigs = 3 × 40 g = 120 g.
  3. Total weight = 360 g + 120 g = 480 g.
  4. Convert to kilograms: 480 g ÷ 1000 = 0.48 kg.
Common mistake: Forgetting to convert grams to kilograms

Concept tested: Weight calculation of natural materials
