Question

formula of diagonal of cube and cubiod​

Answer 1

Diagonal of a cuboid=l^2+b^2+h^2.

Diagonal of a cube = √3 a.

(Whereas lbh refers to length, breath and height respectively ; a is edge of a cube).

Please follow me and thank my answers.

Answer 2

HI !

Formula for finding the length of diagonal of cube :-

Let the edge of a cube be "a"

Then the length of diagonal is √3 a

------------------------------------------------

Formula for finding the length of diagonal of cuboid :-

Let the length and breadth  and height of the cuboid be "l" and "b" and "h" respectively

Length of diagonal :-

$\sqrt{ l^{2} + b^{2} + h^{2} }l2+b2+h2$
