Describe or show two different ways to find the volume of a right rectangular prism with dimensions of 9 centimeters by 7 centimeters by 12 centimeters.

Sorry for the other person, he was no help

Step-by-step explanation:

One way is to multiply 7x12 then divide that by 2 because its a triangle then you will multiply that by 2 because there are two triangles which would give you 84  then you multiply 7x9  and get 63 and multiply that by 3 because there are 3 rectangles and you get 189

Another way is to do 7x9x3=189/ 7x12=84  then you do 84+189 which is 273

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

hope this you
