For this case, the first thing to do is find the volume of the tank.
 We have then:
 V = (12) * (9) * (8)
 V = 864 feet ^ 3
 Then, the cost of filling half the tank is given by:
 C = (1/2) * (1.82) * (864)
 C = 786.24 $
 Answer:
 It costs to fill the tank to one-half of its capacity about:
 C = 786.24 $
