Worked Solution
Step 1: Identify the 3 pairs of opposite faces and their areas.
Top and bottom faces: 8 cm × 5 cm = 40 cm² each → 2 × 40 = 80 cm²
Front and back faces: 8 cm × 3 cm = 24 cm² each → 2 × 24 = 48 cm²
Left and right faces: 5 cm × 3 cm = 15 cm² each → 2 × 15 = 30 cm²
Step 2: Add all face areas.
80 + 48 + 30 = 158 cm²
Answer: 158 cm²
Note: The area of the net equals the total surface area of the cuboid.
Correct answer: 158 cm²
