    Given :

    Radius of cylinder = 7cm

    Total surface area = 968cm²

    Let the Height of the cylinder be ‘h’

    As we know

    Total surface area of cylinder

    = 2πr( r+ h )

    2 × 22/7 × 7( 7+ h)

    44/7 × 49 + 7h = 968

    308 + 7h = 968

    7h = 660

    h = 660/7

    so required height is 660/7 cm
