Help pls What is the volume of this composite solid?

D

Step-by-step explanation:

First, we can find the volume of the rectangular prism.

As shown in the image, the dimensions are 4 by 4 by 9.

So,

4 * 4 * 9 = 144.

Now, we find the volume of the triangular prism.

As shown in the image, the dimensions are 3 by 4 by 9.

So,

3 * 4 * 9 = 108.

Now we add the volumes together:

144 + 108 = 252.

So, the answer is option D: 252 cubic meters.
