Total surface area = inner curved surface area + outer curved surface area + area of 2 rings
We will consider ,
R=outer curved surface area
r=inner curved surface area
h=given lenght
=2πRh + 2πrh + πR^2 + πr^2
=π(r +R )+(2h + R-r )
After solving with values we will get the total surface area as 253.88 cm ^2
