Answer 1

Answer:

364 cm²

Step-by-step explanation:

closed tea box means a cuboid with all faces

A cuboid has 6 faces

2 faces with 10 cm ×8 cm

2 faces with 8cm × 6 cm

2 faces with 10cm × 6 cm

So, area of cardboard required is

2 × (10×8 + 8×6 + 10×6) cm²

2 × (80+42+60) cm²

2× 182 cm²

364 cm²
