Question
The lateral surface area of a cube is 400
cm2. The length of a cuboid is 50% more than the side of the cube. The breadth of the cuboid is 12 cm less than its length and 40% less than its height. Find the total surface area of the cuboid.Solution
Let the length of the cube be ‘a’ cm
According to the question,
4a2 = 400
=> a2 = 100
=> a = 10
Therefore, length of the cuboid = l = 1.5 × 10 = 15 cm
Breadth of the cuboid = b = 15 – 12 = 3 cm
Height of the cuboid = h = 3/0.6 = 5 cm
Therefore, total surface area of the cuboid = 2(lb + bh + lh) = 2 × {(15 × 3) + (3 × 5) + (15 × 5)} = 270 cm2
