# How many segments on a gridded cuboid?

Hello everyone,
So let's say we have a cuboid.
On the X axis, it's divided to 4 segments (i.e. by 3 lines parallel to z axis) (segx=4).
On the Y axis, it's divided to 3 segments (i.e. by 2 lines parallel to z axis) (segy=3).
On the Z axis, it's divided to 8 segments (i.e. by 7 lines parallel to x or y axes) (segz=8).
Each line between two grid points is called a segment. How many segments are there on the surface of this cube entirely? All the 6 sides are divided as I said (it looks like Rubik's cube!).
The numbers I said were just an example. I need a formula based on segx and segy and segz for the number of segments on this cuboid.
I'm working on an algorithm this is needed for. I appreciate any help.
Thank you so much

hello boyboy400!

you'll need to count the segments on each face separately, and then add for all six faces

(except, don't forget not to count the "edge" segments twice!)
