Answer 7

Answer 8

It looks just like your drawing. I think the volume listed in your question was mis-typed.

Answer 9

so... let us find the height of the box first off
notice, the box is as high as the "triangle's altitude"
thus

Answer 10

now, for part B
what is the amount of cardboard to be used? well, that is
what is the surface area of the prism?

well, notice the picture here
is a triangular prism, but notice, is really just
2 triangles and 3 rectangles, stacked up to each other at the edges

now, to get the "surface area" of the prism
just find the area of each of those fellows
the area of the two triangles, and the three rectangles
and SUM THEM UP :)
