12 edges

The number of edges of the base of a prism can be used to calculate the total number of edges by first determining the number of edges on one base. For example, a rectangular prism has 4 edges on its base. Then, multiply this number by 2 to account for the top and bottom bases. Finally, add the number of edges around the sides of the prism, which is the same as the number of edges on the base. So, in total, the number of edges of a prism can be calculated as 2 times the number of edges on the base plus the number of edges around the sides.

Oh, isn't that a happy little question! Let's think about it together. A prism has 2 bases and the same number of edges as the number of sides on those bases, plus the number of edges connecting the corresponding vertices on the bases. So, a prism can't have seven more edges than vertices because the number of edges is determined by the number of sides on the bases and the number of vertices.
Yes.
Yes because there are 12 edges in a prism and 12 is indeed a multiple of 3
all of its edges are straight
None. A prism can have only straight edges.

They are straight lines.
There are twelve edges in a rectangular prism.
Because a rectangular prism has straight edges whereas a a cylinder has curved edges.
