When a rectangle is folded into a cylindrical shape, the area of rectangle becomes the curved surface area of the cylinder.
dimension of rectangular metal sheets are:
l = 15cm
b = 12cm
area of rectangle = l×b = 15×12 = 180 cm²
So CSA of cylinder = 180 cm²

l = 15cm
b = 12 cm
area of the rectangle will be equal to cylinder
area of rectangle = lxb

= 180
area of the rectangular metallic sheet = 180cm²
therfore, CSA of cylindrical shape = 180cm²
