If the answer in the picture is not correct then do this. After the volume is calculated , calculate the surface area whose formula is 3.14( (D^2 + d^2) + whole root of (D^2 - d^2)^2 + (h(D+d))^2 The above will give the surface area which is 8543.4 cm^3 and then multiply by 1.20 = 8543.4 x 1.20 = Rs 10252 Sorry for the inconvenience
