There is not enough information to answer. What is the shape of the tank? How cold is it? How efficient is the heating system? How large a space are you heating?
To get a specific answer, we'd have to know the size of the tank. Since you used "an", let's assume an 18 gallon tank. 18 x 2.999 = 53.982. Rounded to the nearest cent (hundredth), that's $53.98

You actually have a 20 gallon tank. There are 231 cubic inches in a gallon. So if you take your length times your with you get: 24x12 = 288in square. Then multiply that times the 16 inches of height and you get 4,608 inches cubed. Divide that number by the 231 cubic inches per gallon and you get: 4608 (inches cubed)/ 231(cubic inches per gallon)=19.94 Gallons or a 20 gallon tank.
