Worked Solution
Step 1: Identify the three pairs of faces on a cuboid.
• Top and bottom: length × breadth = 6 × 4 = 24 cm² each → 2 × 24 = 48 cm²
• Front and back: length × height = 6 × 2 = 12 cm² each → 2 × 12 = 24 cm²
• Left and right: breadth × height = 4 × 2 = 8 cm² each → 2 × 8 = 16 cm²
Step 2: Add all six faces: 48 + 24 + 16 = 88 cm²
Answer: Total surface area = 88 cm²
Answer: 88 cm²
Correct answer: 88 cm²
