Question

If diagonal of q is root 12cm.then volume is cubic cm is

Answer 1

Hey

Side of a cube = a
Length of a Diagonal in a cube = √3a = √12 cm
 √3a = √12 cm
 a = √12 ÷ √3
 a = √ 4                     [ √ 4 = 2 ]
 a = 2
 
Side of the cube = 2 cm

As we know , 
Volume of a cube = a³
                             = 2³
                            =
$8 {cm}^{3}$

Hope it helps to you.
