Which expressions will help you find the surface area of this right triangular prism? Select all that apply.

11 × 3
1/2 × 3 × 5
4 × 11
5 × 11

We need to know the area of all of the faces, so let's break this down into the triangles and rectangles.

Triangles:

1/2(3 x 4)

-You would need to multiply this expression by 2 to find the areas of both triangles, but this expression would help you to find those areas.

Rectangles:

5 x 11

4 x 11

3 x 11

Hope this helps! :)
