A cuboid is a 3 dimensional rectangular shape for example a box of Kellogg's Conflakes. If you count all the edges (lines) you will have 12.
So total = 12 edges

See the pattern? This is similar to Pascal's Triangle, but you add twice the left parent to the right parent.
The rows give you the answer. The top row gives the number of points in a point.
The second row counts the number of 1d and 0d "squares" in a line, 1 and 2.
The 3rd row counts 2d, 1d, 0d "squares" in a square: 1, 4, 4.
The 4th row counts 3d, 2d, 1d, 0d "squares" in a cube: 1 6 12 8
The 5th row counts 4d, 3d, 2d, 1d, 0d "squares" in a 4d cube: 1, 8, 24, 32, 16.
This pattern continues, so you can find your answer for higher dimensional squares also. (and investigate why this works, and what it means)

12 edges

Look at a pack of cards.
The top surface of the pack shows 4 edges.
The bottom surface of the pack shows another 4 edges.
The top surface is connected to the bottom surface of the pack by 4 more edges.
That makes 12 in all.
