Daily dose of logic



Hey, can someone explain it please

In order to solve this question you have to calculate at first the whole area that should be painted for the two sheds and after that you’ll multiply that number by 3 because you need 3 coats and by 4 because it takes 4 minutes to paint 1 meter squared. After that, just add 20 min which are for the coffee break. The solution would be as follows.
area of 1st side(without the door) A1= 2x1=2 squared meters
area of 2nd side(with door) A2=2.5x1=2.5 squared meters
total area for 2 sides =2+2.5=4.5
but for 1 shed you have 4 sides, 2 of each then you have
4.5x2=9 squared meters per 1 shed
you have 2 sheds then 9x2=18 squared meters
each square meters needs 4 min then 18x4=72 min
you need 3 coats the, 72x3=216 min
finally, 216min+20 min=236 min which gives you 3 hrs and 56 mins
