Answer 1

it's only asking for the exterior faces, so let's list out all the faces that face outwards

- two squares with length and width x (one in the front one in the back), so 2*x*x
- the left and right rectangles with width y and height x, so 2*x*y)
- the bottom side (another rectangle with width y and height x
- two triangles with base w and height w, (1/2)(w)(w)
- the two rectangles off the side of the triangle, with length y and width x, so 2*y*z

add up all the areas, plug in the appropriate values from the problem
