Question
The volume of a cuboid whose length, breadth, and height
are in the ratio 5:3:2, respectively, is 3,000 cm³. Find the lateral surface area of the cuboid.Solution
ATQ, Let the length, breadth, and height of the cuboid be '5a' cm, '3a' cm, and '2a' cm, respectively. Volume of cuboid = length × breadth × height 
Lateral surface area of the cuboid = 2 × (length + breadth) × height = 2 × (5a + 3a) × 2a = 16a²=16×(10)² = 1,600 cm²
2*1/3 + 22*1/3 + 222*1/3 + 2222*1/2 + 22222*1/2 = ?
