V = a3
d = √3 a
V = d3/(3x√3 )
= 63/(3x√3 )
V = 41.57 m3

Given :- Diagonal = 6m
Formula for Diagonal
=> √3a ( where a is side of the Cube )
√3a = 6
a = 6 /√3
a = 2√3
Formula for Volume
=> a³ ( where a is side of Cube )
Volume = a³
= ( 2√3 )³
= 8 × 3√3
= 24√3 m³
Volume of Cube = 24√3 m³

How that 2 came can anyone say
when 6 is factorise it gave 2 ×3
3 can be written as √3 ×√3
one √3 is cancelled then 2√3 we get!
