Step 1: Convert Box A to grams. Box A = 1 kg 650 g = 1650 g Step 2: Find the mass of Box B. Box B = Box A + 480 g = 1650 + 480 = 2130 g Step 3: Find the combined mass of Box A and Box B. Box A + Box B = 1650 + 2130 = 3780 g Step 4: Find the mass of Box C. Box C = ½ × 3780 = 1890 g Answer: 1890 g Answer: 1890 g
