2 walls are 3' x 10'
+2%2A%28+3%2A10+%29+=+60+
2 walls are 28' x 10'
+2%2A%28+28%2A10+%29+=+560+
--------------------
(A) The surface area of the 4 walls is +60+%2B+560+=+620+ ft2
--------------------
( cost / ft2 ) x ( total ft2 ) = total cost
+%28+150+%2F+30+%29%2A620+=+3100+
(B) The cost of siding is $3,100
