Comments

There is one ball because they asked how many ball are in the picture. Smart 6th grader right here.

Answer 1

1. Number of balls visible in the picture = 16

2. If we perceive this as 3D arrangement and need to add the hidden balls as well, then there are 2 possibilities:
   a. Triangular arrangement
   total number of balls = 10 + 6 + 3 + 1 = 20

   b. Square arrangement
   total number of balls = 16 + 9 + 4 + 1 = 30

So, based on perspective, number of balls can be either 16 or 20 or 30.

Comments

The bottom is arranged with 90 degree right angles.. therefore the only 2 logical answers are 16, or 30

It can not be triangular as 4 x 4 base is visible

Answer 5

30 balls
4 x 4 = 16 lowermost base

Answer 6

4 balls.

The four full spheres in front standing on top of each other can be considered as balls. The others are partially blocked and we don't know whether they are fully sphere or not. So there are 4 balls..
