Help with math question plz. 12th grade

C

Step-by-step explanation:

To find the volume of a rectangular prism, you need to multiply the width by the length by the height (the three given side lengths).

Only C and D do that. Meanwhile A and B just add them, which is not what you're supposed to do.

So, we know it's not A or B.

After finding the volume of each of the prisms, you need to add them to find the combined volume.

D multiplies them, so it's not D.

Therefore it must be C, which correctly multiplies the side lengths and then adds the volumes together at the end.

the first one, all those points on the line just make a strait line.
