Question

Find the diagonal of the cube whose each edge is 12 cm.​

Answer 1

We can find length of diagonal of a cube very easily using its sides by the use of the formula finding the diagonal of the cube which is

$diagnal \: of \: cube = \sqrt{3} a$

where a is the given edge of the cube.

____________________________

Given that edge of a cube is equals to 12 cm.

So ,

a = 12cm.

As , we know that

$diagnal \: of \: cube = \sqrt{3} a$

So,

$Diagonal = \sqrt{3} \times 12 \\ 12 \sqrt{3} cm$

so, diagonal of the given cube will be

$12 \sqrt{3} cm$

Answer 2

Step-by-step explanation:

Here , given that the edge of the cube =12cm

As we know ,

Diagonal of cube = √3 (x)

=√3(12)

=12√3 cm
