Question

Diagonal of cube is root12 cm. What is lebth of is edge.

Answer 1

Let the length of the cube be x cm.
Diagonal of the cube = {3^(1/2)× x } cm

According to the question,
=>3^(1/2)× x=12^(1/2)
=>x=12^(1/2)/3^(1/2)
=>x=12/3^(1/2)
=>x=4^(1/2)
=>x=2

Therefore, the length of the cube is 2 cm.

Answer 2

Answer:

The answer is 2 cm.

Step-by-step explanation:

Let the length of the cube be x cm.

Diagonal of the cube = {3^(1/2)× x } cm

Now,

3^(1/2)× x=12^(1/2)

x=12^(1/2)/3^(1/2)

x=12/3^(1/2)

x=4^(1/2)

x=2
