Question

The diagonal of cube is √12.what is it's edge

Answer 1

Answer:

Step-by-step explanation:

Given length of diagonal of a cube = √12 cm

Recall that length of diagonal of a cube = √3 × Length of edge of the cube

⇒ √12 = √3 × Length of edge of the cube

∴  Length of edge of the cube = √12 / √3

                                              = 2√3 / √3 = 2

Thus the edge of the given cube is 2 cm

Answer 2

Answer is 2

$d = \sqrt{3} a \\ a = \frac{d}{ \sqrt{3} } \\ a = \frac{ \sqrt{12} }{ \sqrt{3} } \\ a = 2$
