A standard 3x3x3 Rubik's Cube has 12 edges.
These edges are the pieces that sit between the corners and only have two colored stickers. Understanding the composition of a Rubik's Cube is key to solving it, and recognizing the number of edges is part of that foundational knowledge. Each edge piece consists of two colored faces, and their position relative to the corner pieces dictates how they can be manipulated during the solving process.
