Ratios of Similar Solids: From Area to Volume

The diagram shows two geometrically similar pots with a circular base.
It is given that the height of pot \(A\) is \(30\) cm and the base area of pot \(B\) is \(\frac{4}{9}\) of the base area of pot \(A\).

1. Calculate the height of pot \(B\).
2. The curved surface area of pot \(B\) is \(260\) cm\({}^2\).
   Find the curved surface area of pot \(A\).
3. If the capacity of pot \(A\) is \(5.4\) litres, find the capacity of pot \(B\), giving your answer in cm\({}^3\).
