ATQ, Quantity I: smallest two-digit number, 'y' = 10 Lateral surface area of cube = 4 × (Edge)2 Therefore, required area = 4 × 102 = 4 × 100 = 400 cm2 So, Quantity I = 400 cm2 Quantity II: Breadth of cuboid = 0.75 × 20 = 15 cm Lateral surface area of cuboid = 2 × (Length + Breadth) × Height Therefore, required area = 2 × (20 + 15) × 6 = 2 × 35 × 6 = 420 cm2 So, Quantity II = 420 cm2 Therefore, Quantity-I < Quantity-II
