Answer:
Step-by-step explanation:
The heights of neither the rectangular prism nor the triangular prism are given, so we don't know the volume of either.
If h is the height of the rectangular prism, then its volume is
6Ă—8Ă—h = 48
if the height of the triangular prism is h/2, then its volume is
(1/2)Ă—24Ă—8Ă—(h/2) = 48
So we know the volumes are the same -- but we don't know what that volume is.
