Since they are similar \[\sqrt{\frac{A_1}{A_2}} =\sqrt[3]{\frac{V_1}{V_2}}\]\[\sqrt{\frac{605}{A}} =\sqrt[3]{\frac{1331}{729}}\]\[\sqrt{\frac{605}{A}} =\frac{11}{9}\] Can you get A ( surface area of the smaller solid ) from here?

I still do not fully understand , I think the answer is 405

The answer is 405.. For similar figure, (ratio of the length)^2 = ratio of the area (ratio of the length)^3 = ratio of the volume So, take square of area and take cubic root of volume, you'll get the ratio of the sides, which should be equal.
