To calculate the volume of a figure made up of two rectangular prisms, we need to determine the volume of each prism and then add them together.

The volume of a rectangular prism is given by the formula:

$V = \text{length} \times \text{width} \times \text{height}$

If you provide the dimensions of the two prisms, I can calculate the volume for you and verify which of the given answers is correct.

Do you have the dimensions for the prisms?
