Hey everyone!

Could someone explain why there are 18 and not 17 cubes. That cube on the right...it looks like there's not even supposed to be a cube there.

Kinda weird.

Any feedback helps. Thanks!

I got 18 as well, first layer is 10 cubes, second layer 5 cubes, third layer, 2, fourth layer 1 cube. You are probably missing a cube on the first layer. the row on the first layer on the most right has four cubes, row to the left, three, row to left two, and the last row has one cube.

How do you know the second to last row has 2 cubes on the bottom? It seems like you have to assume there is a cube there.

One of the assumptions you make is continuity.

Yes, you can also use parallel lines to guess where they are located, if they don't vividly show any holes, assume there is a cube there instead of a blank space.
