Answer 12

The slant height is different from the height going from the base to the top of the pyramid: http://www.ck12.org/geometry/Surface-Area-and-Volume-of-Pyramids/lesson/Pyramids/

Answer 13

This is not a volume problem but a surface area problem.
Find the area of 1 triangle that forms the side of the pyramid. Multiply it by 4.
Add the area of the square base.
