Answer

You have to actually count all the balls in the pyramid.
Simple way is to count the balls in each level.


So lower most level lets say 1st level has 4 x 4 balls; i.e. 16 balls
Similarly 2nd level has 3 x 3 balls; i.e. 9 balls.
3rd level has 2 x 2 balls; i.e. 4 balls.
The top most level has just 1 ball.


So the total number of balls is 16+9+4+1 = 30.


 


So the image has 30 Balls in all.
