Ijust need to know if they have equivalent volumes and an explanation.

Yes, they have equivalent volumes.

Step-by-step explanation:

For the volumes to be equal, a would have to be equal to b. We'll assume x=x

1. Set the volumes equal to each other

x +a +2b =x +2a +b

2. Simplify

[x +a +2b =x +2a +b] -x

[a +2b =2a +b] -a

[2b =a +b] -b

b =a

Therefore, 2a=2b, a=b, and x=x

Since the two prisms have the same measurements, they have the same volumes.
