To find the volume of a triangular prism, you can find the area of the base triangle, and multiply that value by the height of the prism.
So let's first find the area of the base triangle (which is its base times height, divided by 2):
\frac{b \times h}{2} = \frac{4.5\times3}{2} = \frac{13.5}{2} =6.75

Then, multiply this value by the height of the prism, which will give you the prism's volume:
6.75 \times 9=60.75

Your answer is 60.75 miles³, or option 2.

1. = Step 1. Simplify Brackets and you get 12.5 - 31.5 Step 2. Simplify and you get -19&#10; which is your answer.

2. = Step 1. Simplify Brackets and you get -31.91-16.7 Step 2. Simplify and you get -48.61

3. = Step 1. Simplify Brackets and you get \frac{1}{6} - \frac{11}{12} + \frac{2}{3} Step 2. Simplify and you get - \frac{1}{12}

4. Step 1. = Simplify Brackets and you get 29-15.7-31.05 Step 2. Simplify and you get -17.75
