If edge of a cube is 12 metres, then the diagonal of each side is_____

1.	If edge of a cube is 12 metres, then the diagonal of each side is_______-
Answer» ong>Answer: 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} adiagnalofcube= 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} adiagnalofcube= 3 a So, \begin{gathered}Diagonal = \sqrt{3} \times 12 \\ 12 \sqrt{3} cm\end{gathered} Diagonal= 3 ×12 12 3 cm so, diagonal of the given cube will be 12 \sqrt{3} CM12 3 cm

ong>Answer:

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} adiagnalofcube=

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} adiagnalofcube=

So,

\begin{gathered}Diagonal = \sqrt{3} \times 12 \\ 12 \sqrt{3} cm\end{gathered}

Diagonal=

×12

so, diagonal of the given cube will be

12 \sqrt{3} CM12
