hii!!
here's ur answer...
volume of the cubical vessel=216cm³
therefore side³=216cm³
→ side = ³√216
→ side = 6cm
verification:-
volume of the cubical box=side³
= 6×6×6
= 36×6
= 216cm³
hence verified
thus the side of the cubical box is 6cm.
we have to find the area of metal required to make the box without the lid.
so we have to find it's CSA+1base
let a be the side of the cubical box
CSA+1base of cubical box=5a²
= 5×(6)²
= 5×36
= 180cm²
hence 180cm² of metal is required.
hope this helps u..!
