Below is a diagram of a rabbit tunnel in the shape of a triangular prism.
What is the volume of the tunnel?

Answer: 412.5cm cubed
Step-by-step explanation:
Volume of a prism: area of base ( in this case it’s the triangle) times the height
First: half x 90 x 120 = 165
Then times the height
So, 164 x 2.5 = 412.5
