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
