Question 1112193
2(15 x 8) = 240
2(30 x 8) = 480
. . . . .---------
Total : 720 this is the total square footage Max is going to paint. Since he will require 2 coats, Max will double this:
1st coat: 720 squre feet
2nd coat: 720 square feet
. . . . . ---------------
Total : 1,440 square feet
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1,440/350 = 4.11 so this is 4 full gallons.(4 x 350 = 1,400) and he has another 40 square feet to go. For this Max doesn't need a full gallon, he can buy a 1/2 gallon:
4 gallons x 12 = $48
1/2 gallon x 8 = $ 8
. . . . . . . .-------
Total . . . . . $56 This is Max's cost of paint to paint his room with two coats of paint
:
NOTE: this is an easy problem. Be prepared that next they will add windows and door to the room, and you will have to deduct the size of those openings from the square footage to be painted.

Happy learning,
