ANSWER: $84
EXPLANATION:
We need to know the surface area of the room with the specified dimensions.
A = 2(wl + hl + hw)
w = 12
h = 8
l = 16
A = 2( (12 * 16) + (8 * 16) + (12 * 8) )
A = 2(192 + 128 + 96)
A = 2(416)
A = 832 square feet
832 / 150 = 5.546666666666667
(Round that up to the next whole number)
You need 6 gallons, or 6(14) dollars
