Ineed if i have 525 cannonballs to stack, how big of a square base should i create to start with and how many layers tall will the lattice be? (lattice- a square based pyramid)

The number of balls that can be stacked in a square based pyramid is obtained by the sum of the squares of the different lengths of the layers.

Given that the number of the balls to be stacked is 525, the number of layers and the size of the base is obtained as follows:



Thus, an 11 by 11 sized square base with 11 layers will use up 506 cannonballs remaining 525 - 506 = 19 cannonballs
