Question

What is the formula to find the diagonal ??​

Answer 1

Answer:

1. To calculate a diagonal of a square, multiply the length of one of the square's sides by the square root of 2. If you don't know the length of one side, you can find it by plugging the square's perimeter into the formula: perimeter = 4s, where s is the length of one side
2. The formula to find the number of diagonals is n(n - 3)/2, where n is the number of sides the polygon has.
3. If l, b and h denote the length, breadth and height respectively of the cuboid then the length of its diagonal d is given by the formula d = √(l^2+b^2+h^2).
