Aright triangular prism has a height of 3 ft, a width of 4 ft, and a hypotenuse of 5 ft. the depth of the triangle is missing. if the surface area of the triangular prism is 192 square ft, find the depth of the triangular prism.

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
