You can put this solution on YOUR website! 2*11*8+2*17*8=176+272=446 area of the walls.
11*17=187 area of the ceiling.
2(3*4)+(2.5*6.5)=2*12+16.25=24+16.25=40.25 area of the windows & the door.
446+187-40.25=592.75 ft^2 for the area to be painted.
592.75/80.88=7.329 gal. of paint will be required.
8*19.11=$152.88 cost of the paint.
