For part 1, are you able to use the calculator for this?
Simply cube root 21952 and you'll get 28cm (which is the length of each side of the cube, or the length of each plastic stick)
For part 2, recognize that a cube framework is constructed using 12 sticks; hence, total length of sticks is simply 12 × 28 = 336cm
