To find the volume of a rectangular pyramid with a scale factor of 3, we can use the fact that the volume of similar solids changes with the cube of the scale factor.
If \( V \) is the volume of the original pyramid, the volume \( V' \) of the new pyramid with the scale factor \( k \) (in this case, \( k = 3 \)) can be calculated using the formula:
\[ V' = k^3 \times V = 3^3 \times V = 27 \times V \]
Since we don't have the volume of the original pyramid provided in the question, we can't calculate the new volume directly. However, you can find the original volume, multiply it by 27, and choose the correct option from the answers provided based on that calculation.
If you have the original volume, please share it, and I can assist you further in calculating the new pyramid's volume. If you assume any of the options given is the original volume, you can find the new volume based on that.
