Assuming the top of the shed has a roof it is not to be painted, the bottom is not to be painted either. dealing with just the sides you only have to calculate 4 panels instead of 6.

unfolding the shed, like it was a piece of folded paper, you now have to only deal with 4 sides.

2.5+2.5+2.6+2.6 = 10.2m

10.2m x 2m = 20.4 m^2

20.4 x 2 = 40.4 m^2

40.4 : 4 = 10.1

11 tins
