enny is planning to texture$-$coat a building whose dimensions are shown below. The front of the building has a window measuring $39$ in by $4$ ft and a door neasuring $3$ ft by $80$ in$.$ The left and right sides of the building each have a window measuring $16$ ft by $4$ ft$.$ The back of the building has no window or door. se the given information to answer the questions. Each tab shows a different view of the building. $($a$)$ Assuming the roof, windows, and door require no texture$-$coat, what is the area in square feet that needs texture$-$coat? $($Do not round any intermediate computations and give your answer as a whole number.$)($b$)$ Jenny will use texture$-$coat that is sold in cans. Each can contains enough texture$-$coat to cover $270$ ft$^2.$ Assume Jenny doesn't have any texture$-$coat yet and she can't buy partial cans. How many cans will she need to buy in order to texture$-$coat the building? cans
