Question

diagonal of a cube is root 12 cm what is the length of its edge?

Answer 1

dia - root 3 a

so root 12 = root 3 a

so a is 2

Answer 2

Answer:

2 cm

Step-by-step explanation:

Diagonal of cube = √12

Formula of diagonal of cube = √3a

Where a is the side

So, $\sqrt{12} =\sqrt{3} a$

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

$\sqrt{4}=a$

$2=a$

Thus the side of cube is 2 cm

Hence the length of the edge of cube is 2 cm.
