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?

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 а bout:

C = 786.24 $
