A right square prism has a volume of 75 cubic inches. The prism is enlarged so its height is increased by a factor of 5, but the other dimensions do not change. What is the new volume? A. B. C. D.

The new volume is 375 cubic inches.

Step-by-step explanation:

Volume of a right square prism:

The volume of a right square prism is given by:

In which a is the length of the edge and h is the height.

A right square prism has a volume of 75 cubic inches.

This means that:

The prism is enlarged so its height is increased by a factor of 5

Edge is the same, height is 5 times. So

The new volume is 375 cubic inches.

y=mx+b is the final answer!   : )

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
