The surface area of the prism is square units. all measurements in the image below are in units. (input whole number only.)

The orientation of the solid is odd, but here is what I see.

24+24+39+52+65= 204 units^2

Hello!

To solve, we find the area of each face of the triangle.

As there are two triangles, we can just multiply the side lengths of one of them without using the 1/2 in the formula as there are two triangles.

This means that the two triangle faces equal 48 square units.

For the base, hypotenuse and back, we will just multiply their side lengths.

6·6.5=39
6.5·10=65
8·6.5=52

Now we add up all these values, including 48 from the triangles.

This gives us 204 square units as our final answer.

I hope this helps!
