Here you go.
The trick is: We want full circles, so for both the length and the breadth, they must fit in an entire circle.
Along 6m length, we can fit at most 7. If we try to squeeze in 8: 8 x 0.8m = 6.4m, more than 6m.
Along the 4m height, we can fit 5 of them nicely.
So in total, there can be 7x5 = 35 circles cut out.
