Question

If the diagonal of a cube is √12cm. find it's edge? ​

Answer 1

length of diagonal = √3 × Length of edge  

√12 = √3 × Length of edge of the cube

Length of edge of the cube = √12 / √3

 = 2√3 / √3 = 2

Answer 2

Step-by-step explanation:

$\sf \: diagonal \: of \: cube \: = \sqrt{3} (edge)$

$\sf \: diagonal \: = \sqrt{12} cm$

$\sf \: \sqrt{12} = \sqrt{3} (edge)$

$\sf \implies \: edge \: = \frac{ \sqrt{12} }{ \sqrt{3} }$

$\sf \implies \: edge \: = \sqrt{4} \\ \sf edge=2 cm$
