Length of rectangular piece = 77 cm
With of rectangular piece= 30 cm
Area of rectangular piece = 77×30=2310cm sq
Height of cylinder= 30cm ( because rectangular piece Rolled around width)
Curved surface area of cylinder= area of rectangular piece
So Curved surface area of cylinder = 2310cm sq
Volume of cylinder=Curved surface area x height of cylinder
= 2310* 30 = 69300 cm cube
