Squares in a rectangle (Posted on 2017-12-15) Difficulty: 3 of 5
144
B4B
B16

The above is a 3*3 grid with B representing black squares.
Reading by rows : 144,4,16; - by columns: 1,441,4,6.
All, except 6 are squares, 4 appears twice – all in all there are five squares.

Create a similar 3*4 grid with no more than 3 black squares , claiming at least six distinct squares.
More than six - welcome!

As in the sample, both repetition and non-square numbers are allowed,
but not counted.

challenging? | Comment 1 of 2
six squares is not challenging, or perhaps I didn't understood it well. 
f.e
1B16
4B25
9B36

There are six 6 squares  just in the rows (no squares in the columns)
