Q1. A metal sheet 27 cm long 8cm broad and 1 cm thick is melted into a cube. The difference between the surface areas of two solids is__________?
Answer: 286 cm²
Explanation: Volume of sheet = 27 × 8 × 1 = 216 cm³, giving a cube of side 6 cm; surface area of sheet = 2(27×8 + 27×1 + 8×1) = 502 cm², cube SA = 216 cm², difference = 286 cm².
