Question

If a storage tank that measures 12 feet by 9 feet by 8 feet is designed to store gas that costs $1.82 per cubic foot, what does it cost to fill the tank to one-half of its capacity?

1 Answer

  • 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 $
