• #### Physics Chapter 1 Measurement Flashcards | Quizlet

Physics Chapter 1 Measurement. Then, with a cross-sectional area of d 2 and a length L, the string occupies a total volume of V = d²L. This is approximately equal to the volume of the ball, given by 4/3 (pi)R³, which is about 4R³ because p is about 3. Thus, we have the following: d²L = 4R³. Solve for L, and you get 2 x 10⁶ m, or about 10³ km.
