Since the object is a cube, times 42 three times by itself. You have to do this because it is length x width x height. 42 x 42 x 42. The answer you're looking for is 74,088 cubic inches because it is three-dimensional.
If you look at the position they all go up one and the value of terms all go up by 3 so 4+1=5 so 5 goes where no is and and 11+3=14
Patterns allow someone to make educated guesses.
