What is the surface area

1500 yd^2

Step-by-step explanation:

First find the area of the base=15*20/2=15*10=150

Then Multiply that by the height which is 10

150*10=1500

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal
