There are 650 cannonballs
we can start from top
we can see that
top has 1 ball
second top has 4 balls
third top has 9 balls
so, we will get series
now, we can add them
we can sum of squares of natural numbers formula
Here , last term is 12^2
so, n=12
we will get
so, number of balls is 650...........Answer
