To solve for the total volume of a dollhouse, we need to know the dimensions of the dollhouse (length, width, and height). However, since the dimensions are not provided in your query, I can't create a specific expression for the volume.
The formula for the volume \( V \) of a rectangular prism (like a dollhouse) is:
\[ V = \text{length} \times \text{width} \times \text{height} \]
If you can provide the specific dimensions of the dollhouse, I can calculate the volume for you. Otherwise, if we simply look at the provided responses, we can conclude that the possible total volumes are:
- 2,640 in³
- 2,400 in³
- 3,120 in³
- 264 in³
If a volume calculation from a provided set of dimensions yields the closest match to one of these options, that would be the correct total volume. If you have dimensions or further information, let me know, and we can compute it together!
