<PRE><B>Question 204059</B>
Areas  are;  ceiling = 15*19= 285
,,,,,,,,,,,,,door  =  3*7 =  (21)
,,,,,,,,,,,,,wall1 = 15*10 = 150
,,,,,,,,,,,,,wall2 = 15*10 = 150
,,,,,,,,,,,,,wall3 = 19*10 = 190
,,,,,,,,,,,,,wall4 = 19*10 = 190
.
,,,,,,,,,,,,TOTAL  = 944
.
944 ft^2 * 1 gallon/ 78.2  ft^2 = 12.07  gallons
.
Problem  says  to  round  up  to  13  gallons,,,,but  this  is  so  slightly  over  
it  would  be  a  waste  to  buy  that  extra.
