Q20. What would be the length of the shortest path between two diagonally opposite corners of a solid (10X10X10) cube?
The shortest path between two diagonally opposite corners of a solid (10X10X10) cube is the space diagonal.
The space diagonal can be calculated using the Pythagorean theorem.
The formula for the space diagonal is √(a² + b² + c²), where a, b, and c are the lengths of the sides of the cube.
In this case, a = b = c = 10, so the space diagonal is √(10² + 10² + 10²) = √300 ≈ 17.32 units.
Q21. If an ant had to travel along the walls, what is the minimum distance between the opposite ends of a cuboid?
The minimum distance between opposite ends of a cuboid is the length of the diagonal of the cuboid.
To find the diagonal, use the Pythagorean theorem: diagonal = sqrt(length^2 + width^2 + height^2)
The length, width, and height of the cuboid must be known to calculate the diagonal
The ant can travel along any of the three pairs of opposite walls, so the minimum distance is the shortest diagonal
Example: A cuboid with length = 3, width = 4, and height = 5 has a diagonal of sqrt(3^...read more

Q93. What is a lambda expression, and how does it relate to functional interfaces? Could you provide an example?
A lambda expression is a concise way to represent an anonymous function, often used with functional interfaces in Java.
Lambda expressions provide a way to pass functionality as an argument to a method.
Functional interfaces are interfaces with a single abstract method, which can be implemented using lambda expressions.
Example: (x, y) -> x + y is a lambda expression that takes two parameters and returns their sum.
