Question

If l is the length of diagonal of a cube of volume v then show 3root3v=l^3

Answer 1

Hii dear here is your answer...

Diagonal Of Cube = √3*Side

Now Side = Cube Root Of Diagonal

Substitute We Get 

√3*3√Volume = √3*3√v

This Is equal to diagonal

Now According To THis Option b) Seems To Be Right One

Simply I Expressed Formula Of Diagonal Of Cube In Terms Of Volume Rather Than Edge

And Check second option

l^3 = (√3*3√v)3 = 3√3*v


hope it helps you....
