What is the formula of diagonal of cube and cuboid?

Solution:

A diagonal is a line segment that joins two vertices of a polygon or a polyhedron.

Let 'a' be the side length of a cube.

The formula for the diagonal of a cube is = 3⎷a

Let 'l' be the length, 'b' be the breadth and 'h' be the height of a cuboid.

The formula for the diagonal of a cuboid is = ⎷(l² + b² + h²)

Thus, the diagonal of a cube = 3⎷a , diagonal of a cuboid = ⎷(l² + b² + h²)]

What is the formula of diagonal of cube and cuboid?

Summary:

Diagonal of a cube = 3⎷a , Diagonal of a cuboid = ⎷(l² + b² + h²)
