Question

Calculate the surface area of this triangular prism.

Answer 1

First you have to find the Area of the triangle:
$A= \frac{1}{2} (b*h)$
So $A= \frac{1}{2} (9*12)$, which is $54$
Now multiply that by the Height of the Triangular Prism:
$V=54*10$, which is equal to 540
Final Answer: $V=540$
