Question

For which figures does it make sense to discuss surface area?

Answer 1

It would be B and E, because they actually 3D. Surface area works on shapes that you can basically see the whole thing, as in, the sides, the face, the back, top, and bottom. A, C, and D are wrong because they are 2D shapes, and you can only see their face, not they entire thing.


 Hope this helped :)

Answer 2

Choices A, C, and D don't make sense since they are not three-dimensional. Surface area deals with 3D shapes, not 2D.
