Answer:
rectangle
Step-by-step explanation:
Answer:
Step-by-step explanation:


Since both equations have
, we can subtract the second equation from the first to try and solve for
:




With this, we can plug the value back into the first equation to solve for
:




Therefore, the solution is 
So you first multiply the found dimensions: 10*3 = 30. Now you have to divide by 2 since it is a triangular prism: 30/2 = 15.
30 (the volume) divided by 15 is 2.
Your missing dimension is 2 feet.
