Answer:
Your answer would be 288
Step-by-step explanation:
You start off with the equation ( V= Bh )
Where "B" represents the area of the base ( which case you multiply 8 and 12 and thus getting 96 as your answer for finding "B")
and Lastly you multiply your "B" with the "h" ( which represents the height) and therefore you multiply 96 and 3
which equals to 288
