let the height be H .
T.S.A of cylinder is 2pai r (r plus h).
T.S.A is 968cm square.
2 into 22/7 into 7 (7 plus H).
44H plus 308 is equal to 968.
44H is equal to 968-308 .
44H is equal to 660.
H is equal to 660/44.
H is 15 cm

Given
R=7cm
H=?
TSA=2*22/7*7(7+H)
968=308+44H
H=968-308
H=660/44
H=15CM
I hope it helps you
