What Is The Formula Of Diagonal Of Cube And Cuboid

What is the formula for the diagonal of cube and cuboid?

A cube, commonly known as the square solid, is a three-dimensional solid. A cube has the same length as all the edges, so its width and height is also the same. All the faces of a cube are in the form of a square. The main diagonal of the cube is referred to as the line segment that runs directly through the cube centre and connects the opposite vertices. 

It has six square faces and sides that intersect at each vertex. Among the five platonic solids, the cube is the only regular hexahedron. It has six faces, twelve edges, and eight vertices. In real life, cubes include sugar cubes, ice cubes, Rubik’s cubes, playing dice, and more. The formula of a diagonal of a cube may compute the face along with main diagonal dimensions. Each face diagonal forms the hypotenuse of the resulting triangle, which is right-angled.

The formula for calculating its diagonal is:

Diagonal of a cube = √3l, l= Length of the side

A cuboid is the three-dimensional counterpart of a rectangle. The main diagonal is the diagonal that runs through the centre of a cuboid; the diagonal that runs through the cuboid’s face is not considered as the main diagonal.

The formula for calculating its diagonal is:

Diagonal of the cuboid =√( l2 + b2 +h2), in which l=length,b=breadth,h=height
