hii!!
here's ur answer...
given the volume of the cube is 729cm³
we know that volume of cube is side³
therefore side³=729cm³
→side=³√729
→side=9cm
verification:-
volume of cube=side³
=9×9×9
=81×9
=729cm³
hence verified.
thus the side of the cube is 9cm.
TSA of the cube=6a²
let the side be a.
=6×9²
=6×81
=486cm²
hope this helps..!
