To find the volume of the new rectangular prism with a scale factor of 12, we first need to calculate the volume of the original rectangular prism, and then apply the scale factor.

The volume \( V \) of a rectangular prism is calculated using the formula:

\[ V = \text{length} \times \text{width} \times \text{height} \]

Given the dimensions of the original rectangular prism:

  • Width = 6 cm
  • Length = 5 cm
  • Height = 4 cm

We can calculate the volume of the original rectangular prism:

\[ V = 6 , \text{cm} \times 5 , \text{cm} \times 4 , \text{cm} = 120 , \text{cm}^3 \]

When we apply the scale factor of 12, the volume of the new rectangular prism increases by the cube of the scale factor. The formula for the volume of a similar shape with a scale factor \( k \) is:

\[ V' = k^3 \times V \]

Plugging in the values:

\[ V' = 12^3 \times 120 , \text{cm}^3 \]

Calculating \( 12^3 \):

\[ 12^3 = 1728 \]

Now, we can find the volume of the new rectangular prism:

\[ V' = 1728 \times 120 , \text{cm}^3 \]

Calculating this:

\[ V' = 207360 , \text{cm}^3 \]

Thus, the volume of the new rectangular prism is \( 207360 , \text{cm}^3 \).

However, if we only consider the initial calculation of the original volumes, it is clear that none of the available response options are correct based on the calculation of \( 207360 , \text{cm}^3 \).

If you have additional context stating otherwise or it requires to choose the best-match among the options provided, please provide clarification.
