Then you need to find the amount of money needed first I multiplied 420 x 37.8 and got 1,5876 then I multiplied 37.8 x 28 and got $1,058.40 and that is how much money it costs to get enough paint to paint the barn.

Me and my partners got $532.
This is what we did to get it: 

Surface area: 
We found the square feet of the walls. 80x30=2,400, 50x30=1,500, and we didn't do the top and bottom since Alexis is just painting the walls.
Then we added them all up to get the surface area. (2,400+1,500)2 = 7,800 ft^2

Cost:
 7,800/420= 18 R 240.
We added one more gallon since there is leftover space. Now we have 19 gallons.
$28 x 19=  $532.
Alexis will need $532 to paint the barn.]]> 2021-02-16 19:04:31 UTC https://padlet.com/garnetvalleyschooldistrict/9cv5dscxs0dafh47/wish/1208340602 https://padlet.com/garnetvalleyschooldistrict/9cv5dscxs0dafh47/wish/1208344278 She will pay $ 1,05
