Karen has this set of three Russian dolls. The largest doll is $13cm$ tall, the next one is $2cm$ shorter and the third one is $4cm$ shorter. Draw up a table to compare the surface area and volume of the three dolls in algebraic terms.

A manufacturer is making pairs of paperweights from metal cones that have been cut along a plane parallel to the base. The diagram shows a pair of these weights. If the volume of the larger (uncut) cone is $128 c{m}^3$ and the volume of the smaller cone cut from the top is $42 c{m}^3$, find the length $x$.
