What is the volume of the following triangular prism?

450 in²

Step-by-step explanation:

All we do is find the area of the triangle at the base and top then  multiply by the height so:

5×12=60

60÷2=30 is the area.

Now as I said we multiply with the height to get our

30×15=450 in²

A

Step-by-step explanation:

base area = (leg 1 x leg2)/2 = (12 x 5)/2 = 30 in^2

V = base area x height of the prism = 30 x 15 = 450 in^3
