Multiply the edge length of one cube.

Answer 1

To check that the volume of the right rectangular prism is correct, the best option from the responses provided is:

Use the formula method to see if the volume is the same.

This means you can calculate the volume of the prism using the formula for the volume of a rectangular prism, which is \( V = l \times w \times h \) (length × width × height). If the calculated volume matches the given volume of \( \frac{7}{8} \) cubic units, then the volume is correct.

The other options do not provide a direct method for verifying the volume calculation in a clear and mathematical way.
