From 1963 to 1986, the volume of the Great Salt Lake approximately tripled while its top surface

Question:

From 1963 to 1986, the volume of the Great Salt Lake approximately tripled while its top surface area approximately doubled. Read the article "Relations between Surface Area and Volume in Lakes" by Daniel Cass and Gerald Wildenberg in The College Mathematics Journal. Then give examples of solids that have "water levels" a and b such that V(b) = 3V(a) and A(b) = 2A (a) (see figure), where Vis volume and A is area.
