Heyyyy mate..
given , Diagonal of cube = 8√3
and formula for diagonal of cube = √3l
√3l= 8√3
l= 8√3/√3=8
l= 8
volume of cube= a^³
8^³= 512cm^³
hence edge of cube = 8 cm and volume=512 cm^³
hope it help you

Let the edge of the cube be x
3√8x=√3-------------->x=8
Edge = 8
Total Surface Area=6(s^2)--------->6*64--------->384cm^2
Total Surface Area = 384cm^2
Volume=s^3---------->512cm^3
Volume = 512cm^3
