Answer:
35.1
Step-by-step explanation:
There's a formula that i've linked as an image
Basically, substitute all 3 sides and the length into that formula, chuck it into the calculator and viola.
Or... we can use pythagoras' theorem and get the height of the triangle Height = [tex]3^{2}[/tex] - [tex]1.5^{2}[/tex] = 2.6
Area of triangle = (3 * 2.6) / 2 = 3.9
Volume = 3.9 * 9
Volume of prism = 35.1
