u need to find surface area which is 2(lw)+2(lh)+2(wh)

so is 2(30x54)+2(30x10)+2(54x10)= 2(1620)+2(300)+2(540)=

3240+600+1080=4920 square feet

divide the amount u need by the amount per gallon so is 4920/400 which is 12.3 gallons

The first term is 2(1) - 9 = -7
the common difference is 2
there are (18 - 1) + 1 = 18 terms in this series
the 18th term is -7 + 2(18-1) = 27

the sum is

sn = 18/2(-7 + 27) = 180
