The document summarizes the calculation of the maximum height (h) that a stack of bricks can be built without toppling over. It determines that: (1) The top brick can extend up to L/2, (2) The second brick extends up to L/4, (3) The third brick extends up to L/6, and (4) The fourth brick extends up to L/8. Adding up the extensions of each brick, the maximum height is calculated to be 25L/24.
