Answer:

There are 650 cannonballs


Step-by-step explanation:

If you look closely in the picture, you can see that:

  • 1st row has 1 ball
  • 2nd row has 4 balls
  • 3rd row has 9 balls
  • 4th row has 16 balls

etc. etc.

We can see that the number of balls is the square of the row number. There are a total of 12 rows. So, rest of the rows has:

  • 5th row has 25 balls
  • 6th row has 36 balls
  • 7th row has 49 balls
  • 8th row has 64 balls
  • 9th row has 81 balls
  • 10th row has 100 balls
  • 11th row has 121 balls
  • 12th row has 144 balls

If we add up all those, we get total number of balls:

1+4+9+16+25=36+49+64+81+100+121+144=650

There are 650 cannonballs
